I believe in you! Don't let those naysayers tell you that you cant do it. I myself have a more impossible quest on learning as much methods as possible, people said that it is not possible and there is no use but i didn't quit and now in my third week i already learned 7 methods!

My advice on getting Sub 8 on Petrus is
1. Petrus is a low move count method so focus on getting your move count very low.
2. I personally practise 1 hour a day but if you have a bunch of time practise for hours and hours per day.
3. Dont give up.

Sub-8 on Petrus:

2x2 block in 1-1.25 secs or faster [Color neutrality is mandatory]
2x2x3 block in 2 secs of faster (in 3 seconds you should finish this stage)

Here, Idk whether you should even do EO or not, but I personally think EO is way too difficult to get fast, otherwise, you're gonna have to be sub-0.5 on EO. Or you can keep blockbuilding and perform VHLS instead.

EO in 0.5 seconds or faster (I just really dont recommend this)
Whole F2L in 2-2.5 seconds or faster (in 6 seconds you should finish this stage)
Last layer in 2 seconds or faster (should be sub-8 when finished)

The hardest part would not be performing the stages, the hardest part is transitioning because to be sub-8, you can not hesitate nor pause at any of these stages. So you're gonna have to train yourself on 100% of your lookahead.

To really maximize your lookahead, ignore every advice you hear from typical cubers about how to practice lookahead. (Things like using a metronome or doing slow solves.)
You're gonna need to use Jayden McNeill's advice on this one. He made a video about it but it's mostly towards CFOP. In CFOP terms, every cuber should study every F2L cases in order to maximize their lookahead. So by performing their comfortable/preferred algorithm on a certain F2L case, not only they must execute the F2L case very fast and blindfolded, but they must observe what happens to other pieces around the F2L pair. Once you study and memorize how other pieces move when executing every F2L cases, you should be able to execute the F2L case and know where each piece will go blindfolded.
So in Petrus terms, you're gonna have to go over all your most common blockbuilding cases that you always execute immediately and observe how other pieces move around the case. This should help you keep transitioning without hesitating to the next stage.

CsTimer is a great tool:
Input your scramble:
3x3 ---> ZBLL (to practice your last layer)
3x3 ---> EOLine then solve a 2x2x3 block (to practice your ZZF2L on your whole F2L stage)
3x3 subsets ---> 3-generator F,R,U (to practice your 2x2x3 block and EO)

I hope this helps. I know you will do it.

This is scary: I actually think it’s in reach

I’ve been cubing for a while now



Jokes aside, thanks for the advice :). I think EO can be done in 0.5 seconds actually, provided you start seeing EO as you finish up the 2x2x3 and influence bad edges. The EO solving algorithms are simple triggers like R U R’ after all.
I’m going to time my splits later and see what I’ll get.

This is mostly good advice except the part about EO, that would just be worse freefop.

I don't usually bother figuring out my splits because I don't think there's much useful information to be obtained (other than the usually obvious fact that every step needs improvement), but this post made me curious since it makes sub 8 sound a lot harder than I would have thought it is.

I recorded my splits for a 8.40 mo8 on my channel just to see my rough splits near an 8 second average.

splits.JPG

Here are my interpretations:

  • From memory, I feel like I was often very lazy with finding the best 2x2x2 in general (not just in this video). I also got the impression watching the video that I often didn't bother to plan out my finger tricks for 2x2x2. So sub 1 2x2x2 seems possible
  • Sub 2 2x2x3 seems not that hard
  • My recognition for EO looks like it could be improved, idk by how much. I think not doing EO is interesting honestly, I experimented with it a bit on my channel (I called it Freefop). It's worth playing around with a bit - your blockbuilding skills should be good enough to get good times with this approach.
  • Sub 2 F2L is seems doable by simply turning faster than me
  • 2.6 ZBLL is about what I average for inspectionless ZBLL scrambles. 2 seconds for ZBLL + recog is ridiculously good, definitely achievable, but it sounds like possibly the hardest way to bring down your time. 2.6 is honestly probably achievable without full ZBLL - but is definitely a lot easier if you learn a few sets at least.
Obviously, you have to use your common sense when interpreting any of this: these are pretty above average solves for me, it's only 8 solves, my timing of splits are probably not perfect and I'm using keyboard instead of stackmat. My opinion on splits remains that it's a waste of time and doesn't tell you anything that would be useful for improvement that isn't obvious anyway. If you want to get sub 8 you're just going to need to improve at every step as much as you can - you don't need splits to know this.

Not doing EO is just FreeFOP.

I'd still consider it petrus. I keep using FreeFOP as from codernunk64.
That method is just simplified hk. Look at the wiki article for freeFOP:

Steps
  1. Solve the first two layers F2L however you wish.
  2. Solve OLL
  3. Solve PLL

    Now look at the wiki page for Petrus:
    [*]The Steps
    The following steps describe an approach suited for beginners, more advanced users might combine steps 1 and 2 and/or 5 and 6 (COLL) or use a Fridrich type last layer and do OLL and then PLL. If the fifth step is skipped the last layer can be solved with a 2GLL algorithm.


    1. Build a 2x2x2 block anywhere on the cube.

    2. Expand the 2x2x2 block to a 2x2x3 block; three ways are possible for each initial 2x2x2 block placement.

    3. Fix the "bad edges" (in other words, orient the remaining seven edges on the cube that have not been solved).

    4. Finish the First Two Layers (F2L) by only turning 2 sides. The pure Petrus approach is to create a 1x2x2 block and expand it to a 1x2x3 block to finish off the F2L, not to solve the cross piece and two corner/edge pairs; two ways are possible. The last-layer edges will orientate themselves automatically.

    5. Permute the last-layer corners (put them in their correct places).

    6. Orient the last-layer corners, making the whole last layer a solid colour.

    7. Permute the last layer edges, without disturbing the other pieces, to solve the cube.

    Petrus clearly has eo in the method. If you don’t do eo, you don’t do Petrus. You do restricted FreeFOP.

I am gonna say
Yes. I want to see how far Petrus can go in speedsolving, compared to other (way) more explored methods such as CFOP, Roux and ZZ. It’ll probably be way harder than just switching to one of the previously mentioned methods, due to the lack of resources and development, but still doable. I predict it to take 3, maybe 4 years starting from now, but hey, I still have a lot of free time on my hands. At the time of writing I am sub 30, but expect that to go down fairly quickly until around sub 15.

So I thought this would be a good place to post my times, ask questions, and hear your thoughts on this.
My plan is to train each of my steps individually for the next few years, improving specifically on certain areas, and putting them together. So lets get into it!


My practise regime for the next few months - work on each step, improving their efficiency then speed. Learn COLLs alongside that. Come back to any weak spots like 2x2x3. Work on inspection time usage. Drill LL algs until like sub 1.5. Practise lookahead as much as possible, use metronome. Start learning full ZBLL alongside other things. Repeat.
———————————————————
Week 1- 2x2x2 block and Sune COLL
Current average: Sub 6
Current No. Moves: 10
Goal:
Sub 5 average
Sub 8 moves
Know all Sune COLL algs
Comment: The sub 5 is getting tricky, as I had to redo my blockbuilding technique, making it easier for low move count, but harder to improve speed, as its unpractised. I know the Sune COLLs now, but need to work on execution and recognition.
———————————————————
Week 2-2x2x2 block and T COLLs
Current average:Sub 7
Current No. moves:8
Goal:
Sub 5 average
Sub 7 moves
T COLLs
Comment: Going to continue trying to get sub 5 averages here, and also lower the move count slightly.
Times with Petrus:
3x3 average: 25.87
3x3 OH average: 1:25.18
3x3 FMC average: 57 HTM
———————————————————
Week 3 - 2x2x2 block and expansion
Current average (both): sub 10
Current No. moves for expansion: 10 (eek)
Goal:
Sub 8 average
Sub 16 moves
Comment: I’m going to try keep my average and move-count down for 2x2x2, and refine my expansion technique. It’s bad. Very bad.
Times with Petrus:
I can’t even post because my times are so bad, as my first two steps have been rebuilt.
___________________________________________
Week 4 - 2x2x2 block and expansion
Current average (both):sub 9
Current No. moves for expansion: 7 (going slowly)
Goal:
Sub 8 average
Sub 16 moves
Comment: Doing better, but still need to wrap my head around this new block building technique, and lookahead.
___________________________________________
Week 5 - 2x2x3 block
Current average: sub 9
Current No. moves for expansion: sub 7 (going slow)
Goal:
Sub 6 average
Sub 7 moves
Comment: Practising lookahead during first block, and using inspection to plan some of the 2x2x3. I actually learnt T COLLs cause why not.
Times with Petrus: Check out my updated records.
——————————————————————
Week 6 - 2x2x3 block and U COLLs
Current average: sub 8
Current No. moves for expansion: sub 6 (going slow)
Goal:
Sub 6 average
Sub 7 moves (normal speed)
Comment: Doing pretty well now, just need to speed it up and lookahead during 2x2x2 block. Copied down U COLLs, started learning. Only 20 more COLLs left! (Obviously I started with 7, that’s 35, then I learnt Sunes, 30, left Anti-Sunes cos not worth it, 25, and did T COLLs, 20.)
——————————————————————
Week 7 - 2x2x3 block and U COLLs
Current average: sub 10 (new technique)
Current No. moves for expansion: sub 8 (I can’t do this sub 6 FMC at even slow speed)
Goal:
Sub 6 average
Sub 7 moves
Comment: My last post on finishing the 2x2x3 up last week was wishful thinking. I’m going to shave off some time on the 2x2x2 through inspection use, and continue my expansion work. I really need to get better at my lookahead during 2x2x2, and CE pair recog (how to pair up, and in a nice place to connect with line)
——————————————————————
Week 8 - 2x2x3 block and U COLLs
Current average: sub 11 to sub 9
Current No. moves for expansion: sub 8
Goal:
Sub 7 average
Sub 8 moves
Comment: This 2x2x3 is taking forever. I just can’t find the pieces in inspection. I’ll try some more and decrease my 2x2x2 time a bit (I think I’m doing well with it) and go back to slow solving. As for the U COLLs, I’m just too lazy to learn. I got two last Saturday, but that’s it.
——————————————————————
Week 9 - Casual solving to get used to technique
Comment: Just going to casually solve, learn some algs, and time myself sometimes. I need a break... So just a week of no dedicated practise, then I’ll get back into it.
——————————————————————
Week 10 - EO training and L COLLs
Current average: sub 5
Goal:
Sub 4 average, maybe 3.5
Comment: All I really need to do is learn all the cases, train my recognition, and spam solves. I’m happy I finished the U COLLs at last lol, now I can move on. I’ll also integrate this with lookahead for finishing F2L, and might try the fixing bad edges during step 2. I think improvement with Petrus is mainly efficiency, and blending the steps together as much as possible, to maintain fluid solving and high TPS.
——————————————————————
Week 11 - EO training and L COLLs
Current average: sub 5
Goal:
Sub 4 average
Comment: Still working on lookahead during 2x2x3. My alg learning laziness isn’t helping with COLL. I could probably learn the whole set in a week if I tried.
——————————————————
Week 12 - Spamming solves & Pi COLLs
Current No. moves for F2L: 30-40
Goals:
Sub 35 movecount for F2L
Be comfortable with everything I’ve
learnt so far
Comments: A bit of time to reflect on what I’ve managed so far, lower movecount, and practise mindlessly. Almost finished COLL :p.
——————————————————
Week 13 - Back to 2x2x3 & Pi COLLs
Current average: sub 8
Goal:
Learn all basic 2x2x3 cases, and work on using inspection for 2x2x2.
Sub 7
Comment: I was originally going to move onto F2L, but decided I couldn’t
ignore my 2x2x3, and that improving there would also help F2L
blockbuilding. It’s one of those steps I can’t improve just by
spamming solves.
I didn’t do Pi COLLs last week, since I was reviewing L COLL
recognition - the hardest so far.
——————————————————-
Week 14 - Finishing F2L and H COLLs
Current average: sub 8
Goal:
Sub 6 with finishing F2L
Comment: I feel like lookahead during EO and TPS while turning RU can be greatly improved so that’s why I’ve set a high bar. As for COLL, I’m almost done, so I’ll be starting ZBLL soon :)
———————————————————————————
Week 15 - Wrapping things up and 2 side COLL recognition
Goal:
Sub 17/8 on F2L
Instantaneous COLL recognition
Comment: Finished off the ‘going round steps‘ thing now :)
———————————————————————————
Week 16 - Competition practise
Goal: sub 20
Comment: Since I’m going to a completion in less than two weeks now, I’m not going to try anything new for the next two weeks, just going to do lots of timed solving.
———————————————————————————
Week 17 - Competition practise
Goal: sub 20
Comment: sub 21 now, maybe I’ll get to sub 20 with some practise before comp. I’m going to start T ZBLLs this week.
———————————————————————————
Week 18 - Planning out 2x2x2 and learning SS T ZBLLs
Goal: Sub 20
Learn last few ZBLLs for the first subset of T
Plan out 2x2x2 every time
Comment: ZBLL started! I’ll do a couple algorithms per day, and drill what I know already along with that. Hopefully, this week, I’ll push to the sub 20 barrier and be able to call myself sub 20 with Petrus (faster than Lars now :)).
———————————————————————————
Week 19 - Drilling Last Layer algs + training SS T ZBLLs
Goal: Every COLL, PLL and ZBLL alg I know, to be sub 2, preferably sub 1.75 with some. SS T ZBLL recognition to be two sided, and almost instant.
Comments: So just some alg spamming, last layer scrambles, and yeah.
———————————————————————————
Week 20 - 2x2x2 efficiency + learning SO T ZBLLs
Goals:
-2x2x2 7 moves or under
-One looking it
-Inspection time to look for as many possibilities as I can
-12 algorithms learnt
Comments: So yeah, I’m going to work on my block efficiency, do slow solving, and also try looking at as many different corners to build the 2x2x2 around as possible in inspection.
———————————————————————————
Week 21 - 2x2x3 efficiency + drilling SO T ZBLLs
Goals:
- 2x2x3 15 moves or under
- Trying to find expansion corner in inspection
- 12 algorithms learnt
Comments: Being lazy with algorithms as usual, need to pick up the slack. I thought it
would be a good idea to expand my inspection capabilities further, so I
set this goal.
———————————————————————————
Week 22 - Break from speedsolving, doing BLD
Goals: Learn full M2, be sub 5 mins
Comments: So, I wanted to try something new for a bit, since if I just keep practising 3x3 speedsolving forever, I will go crazy. BLD seemed like a challenging option, so I went for it. I managed a couple of successes a while back before this thread was even created, but gave up a while afterwards, so at least I won’t be diving in with no knowledge at all.
———————————————————————————
Week 23 - 2x2x2 to 2x2x3 transitioning and LS recognition
Goals:
Sub 4 expansion
No unnecessary AUFs in LS
Comment: So hopefully, this week I will push my lookahead and inspection to the limit, and finally have a decent expansion time. When I finish that, I’ll also look into recognising LS cases better, since I frequently AUF to find the orientation on pieces and things.
———————————————————————————
Week 24 - 2 gen F2L
Goals:
Sub 4.3 F2L
Comment: My two gen blockbuilding tricks could be better, at the moment I do it pretty similar to 2x2x3, individually solving a pair, then connecting it with an edge. I need to pay more attention to where all 3 pieces for the 2x2x1 are before continuing, hopefully I’ll be able to do that during EO. And of course, my TPS could be way better here.
———————————————————————————
Week 25 - Individual steps
Goals:
Sub 4 expansion
Sub 4.4 F2L
Sub 4.2 Last Layer
Comment: It’s a long shot to be able to do this by the end of the week, but I’ll probably give it another week, and hey, maybe I’ll do it, and move onto 2x2x2 and EO.
———————————————————————————
Week 26 - Individual steps
Goals:
Sub 4 expansion
Sub 4.4 F2L
Sub 4.2 LL
Comment: Didn’t so much last week, was slightly ill, I hope to finish off this week :)
———————————————————————————
Week 27- Taking a break
Goals: Not much
Comments: I hope to do some more 4x4 this week, I’m sub 2 min now :)
———————————————————————————
Week 28 - Individual steps continued
Goals:
Sub 4 expansion
Sub 4.4 F2L
Sub 4.2 LL
Comment: I think I’ve got the 2x2x3 now, F2L needs a bit of work most of all. I’ll so some splits today probably.
———————————————————————————
Week 29 - Drilling new techniques + ZBLL
Goals:
Sub 15 average
Half of T set done
Comment: This week will mainly be solves, I’m doing pretty well with my previous goals, and I’m almost sub 15 right now, so I thought I should give myself a chance to stop learning new things and focus on practising what I already know. I haven’t really been learning ZBLL recently, I know a miserable 3/2 of a T subset so far (around 20 algs), along with COLL and PLL.
———————————————————————————
Week 30 - Working on planning 2x2x3 in inspection
Goals:
Be able to see one piece of the expansion in inspection
Comments: In the long run, this will really help with 2x2x3 speed, and it’s definitely going to be needed - it’s basically the equivalent of seeing an X Cross in inspection.
———————————————————————————
Week 31 - Taking a break
Comments: Haven’t been practising much lately, so I’m just going to take a break then get back into it.
————————————————————————————
Week 32 - Drilling F2L
Goal: Sub 4 F2L
Comments: Did some splits last week, concluded my F2L was one of my weaker points. Going to try some 2 gen scrambles.
————————————————————————————
Week 33 - Drilling F2L
Goal: Sub 4 F2L
Comments: Was pretty lazy last week, still need to work on F2L ;)
————————————————————————————
Week 34 - Expansion lookahead
Goal: Sub 4.75 2x2x3
Comment: My blockbuilding is OK once I find the pieces, but generally I take a while to find them, so hopefully I can work on that. I’ll also look into more inspection usage.
————————————————————————————
Week 35 - Expansion lookahead + ZBLL again
Goal: sub 4.75 expansion
Finish learning second T set
Comment: I’m a lazy boi :p
————————————————————————————
Week 36 - Break from 3x3, doing some side events.
Comment: B Day a few days back, I got a Square 1 and 2x2, waiting on a Megaminx too :)
————————————————————————————
Week 37 - Doing some splits, continuing work on 2x2x3
Goals:
Break sub 13.5
Learn a few more ZBLLs
Comments: Back, doing splits right now, hopefully they’ll be better than last time ;) I need to start practising more to be honest.
———————————————————————————
Week 38 - Going back to the old tutorials and lar5.com
Comment: I haven’t really learnt any new techniques in ages, and my blockbuilding style is still quite similar to when I was averaging over 20. I need to go back to the basics, perfect everything. I’ve already tried to do this when I was averaging 25~, but I haven’t learnt everything, which is why I’m going back to my old tutorials to make sure nothing is missed out. For example, lar5.com ‘s example solves and blockbuilding tricks. I never really had the patience to look through them and understand them the last time I visited the site, so I think I need to now, or I’ll never do it. Also I’m getting slightly frustrated with my times not seeming to improve, and just spamming solves, which is another reason for this. My average is probably going to go up after this, like last time, but I think it’ll be worth it long term. My movecount during actual solves doesn’t seem to be very impressive, as shown by my PB ao5, so I’ll have to work on that.
———————————————————————————
Week 39 - Continuing throwback session
Comment: Feel like I’ve learnt all I need to learn from lar5.com. It’s mostly designed to be efficient rather than speedsolvable, so I won’t use a lot of tips, but still found some useful blockbuilding tricks.
I think I’ll look at some of the Erik Johnson tutorials and Tao Yu’s example solves this week.
———————————————————————————
Week 40 - Getting comfortable with new techniques, doing some practise sessions
Comment: Done watching videos, some of it was quite eye opening, and I’m attempting to implement some of the techniques into my solves. I haven’t done a timed solve in a while, mostly slow solving and movecount practise. But I’ll see if I can do some averages near the end of the week.
———————————————————————————
Week 41 - Just an average practise week
Comment: Maybe some solves
———————————————————————————
Week 42 - Taking a break
Comment: Haven’t been properly practising lately, I’m going to... Have one week with NO cubing :O. I’ll come back in a week I think, and update then.
———————————————————————————
Week 43 - Slow, constant solving practise, trying to be as efficient as possible
Goal: Sub 14 with almost pause-less solves
Comment: I thought about it for a while, and decided that slow solving is the solution to my plateau. My solves are surprisingly inconsistent in terms of TPS, with bursts of speed after figuring out a solution.
———————————————————————————
Week 44 - Continuing from last week, focusing on expansion again
Goal: sub 4.5 2x2x3
Comments: Still the weakest point of my solve, need to focus on it. Plus it’s quite inconsistent at the moment. I could just spam solves to break sub 13, but I think that won’t be very helpful long term.
———————————————————————————
Week 45 - Just some solving
Goal: Sub 13
Comment: Been getting consistent 12s and 11s recently. I think I’ll break sub 13 at last soon
———————————————————————————
Week 46 - More solves, and ZBLL restart
Goal: Sub 12?????
Actually learn some ZBLL
Comments: Sub 12 seems kind of far fetched considering how long it took to go sub 13 but bigger goals tend to motivate more. And I feel like I really need to actually start grinding away at ZBLL - it’s been put off for too long.
———————————————————————————
Week 47 - Splits and ZBLL
Goal: 2 T sets of ZBLL done
Try for sub 12
Comment: Refreshed my old algs and memory last week for ZBLL, didn’t get much improvement out of grinding solves then. Will do some splits to practise individual areas
Sub 13 with Petrus now!
Ao5 PB currently 11.391
I am gonna say this, you are the FASTEST Petrus user I have ever seen. Also probably the only petrus user oher than lars petrus. anyway good luck with your quest to sub-8.

Yes. I want to see how far Petrus can go in speedsolving, compared to other (way) more explored methods such as CFOP, Roux and ZZ. It’ll probably be way harder than just switching to one of the previously mentioned methods, due to the lack of resources and development, but still doable. I predict it to take 3, maybe 4 years starting from now, but hey, I still have a lot of free time on my hands. At the time of writing I am sub 30, but expect that to go down fairly quickly until around sub 15.

So I thought this would be a good place to post my times, ask questions, and hear your thoughts on this.
My plan is to train each of my steps individually for the next few years, improving specifically on certain areas, and putting them together. So lets get into it!


My practise regime for the next few months - work on each step, improving their efficiency then speed. Learn COLLs alongside that. Come back to any weak spots like 2x2x3. Work on inspection time usage. Drill LL algs until like sub 1.5. Practise lookahead as much as possible, use metronome. Start learning full ZBLL alongside other things. Repeat.
———————————————————
Week 1- 2x2x2 block and Sune COLL
Current average: Sub 6
Current No. Moves: 10
Goal:
Sub 5 average
Sub 8 moves
Know all Sune COLL algs
Comment: The sub 5 is getting tricky, as I had to redo my blockbuilding technique, making it easier for low move count, but harder to improve speed, as its unpractised. I know the Sune COLLs now, but need to work on execution and recognition.
———————————————————
Week 2-2x2x2 block and T COLLs
Current average:Sub 7
Current No. moves:8
Goal:
Sub 5 average
Sub 7 moves
T COLLs
Comment: Going to continue trying to get sub 5 averages here, and also lower the move count slightly.
Times with Petrus:
3x3 average: 25.87
3x3 OH average: 1:25.18
3x3 FMC average: 57 HTM
———————————————————
Week 3 - 2x2x2 block and expansion
Current average (both): sub 10
Current No. moves for expansion: 10 (eek)
Goal:
Sub 8 average
Sub 16 moves
Comment: I’m going to try keep my average and move-count down for 2x2x2, and refine my expansion technique. It’s bad. Very bad.
Times with Petrus:
I can’t even post because my times are so bad, as my first two steps have been rebuilt.
___________________________________________
Week 4 - 2x2x2 block and expansion
Current average (both):sub 9
Current No. moves for expansion: 7 (going slowly)
Goal:
Sub 8 average
Sub 16 moves
Comment: Doing better, but still need to wrap my head around this new block building technique, and lookahead.
___________________________________________
Week 5 - 2x2x3 block
Current average: sub 9
Current No. moves for expansion: sub 7 (going slow)
Goal:
Sub 6 average
Sub 7 moves
Comment: Practising lookahead during first block, and using inspection to plan some of the 2x2x3. I actually learnt T COLLs cause why not.
Times with Petrus: Check out my updated records.
——————————————————————
Week 6 - 2x2x3 block and U COLLs
Current average: sub 8
Current No. moves for expansion: sub 6 (going slow)
Goal:
Sub 6 average
Sub 7 moves (normal speed)
Comment: Doing pretty well now, just need to speed it up and lookahead during 2x2x2 block. Copied down U COLLs, started learning. Only 20 more COLLs left! (Obviously I started with 7, that’s 35, then I learnt Sunes, 30, left Anti-Sunes cos not worth it, 25, and did T COLLs, 20.)
——————————————————————
Week 7 - 2x2x3 block and U COLLs
Current average: sub 10 (new technique)
Current No. moves for expansion: sub 8 (I can’t do this sub 6 FMC at even slow speed)
Goal:
Sub 6 average
Sub 7 moves
Comment: My last post on finishing the 2x2x3 up last week was wishful thinking. I’m going to shave off some time on the 2x2x2 through inspection use, and continue my expansion work. I really need to get better at my lookahead during 2x2x2, and CE pair recog (how to pair up, and in a nice place to connect with line)
——————————————————————
Week 8 - 2x2x3 block and U COLLs
Current average: sub 11 to sub 9
Current No. moves for expansion: sub 8
Goal:
Sub 7 average
Sub 8 moves
Comment: This 2x2x3 is taking forever. I just can’t find the pieces in inspection. I’ll try some more and decrease my 2x2x2 time a bit (I think I’m doing well with it) and go back to slow solving. As for the U COLLs, I’m just too lazy to learn. I got two last Saturday, but that’s it.
——————————————————————
Week 9 - Casual solving to get used to technique
Comment: Just going to casually solve, learn some algs, and time myself sometimes. I need a break... So just a week of no dedicated practise, then I’ll get back into it.
——————————————————————
Week 10 - EO training and L COLLs
Current average: sub 5
Goal:
Sub 4 average, maybe 3.5
Comment: All I really need to do is learn all the cases, train my recognition, and spam solves. I’m happy I finished the U COLLs at last lol, now I can move on. I’ll also integrate this with lookahead for finishing F2L, and might try the fixing bad edges during step 2. I think improvement with Petrus is mainly efficiency, and blending the steps together as much as possible, to maintain fluid solving and high TPS.
——————————————————————
Week 11 - EO training and L COLLs
Current average: sub 5
Goal:
Sub 4 average
Comment: Still working on lookahead during 2x2x3. My alg learning laziness isn’t helping with COLL. I could probably learn the whole set in a week if I tried.
——————————————————
Week 12 - Spamming solves & Pi COLLs
Current No. moves for F2L: 30-40
Goals:
Sub 35 movecount for F2L
Be comfortable with everything I’ve
learnt so far
Comments: A bit of time to reflect on what I’ve managed so far, lower movecount, and practise mindlessly. Almost finished COLL :p.
——————————————————
Week 13 - Back to 2x2x3 & Pi COLLs
Current average: sub 8
Goal:
Learn all basic 2x2x3 cases, and work on using inspection for 2x2x2.
Sub 7
Comment: I was originally going to move onto F2L, but decided I couldn’t
ignore my 2x2x3, and that improving there would also help F2L
blockbuilding. It’s one of those steps I can’t improve just by
spamming solves.
I didn’t do Pi COLLs last week, since I was reviewing L COLL
recognition - the hardest so far.
——————————————————-
Week 14 - Finishing F2L and H COLLs
Current average: sub 8
Goal:
Sub 6 with finishing F2L
Comment: I feel like lookahead during EO and TPS while turning RU can be greatly improved so that’s why I’ve set a high bar. As for COLL, I’m almost done, so I’ll be starting ZBLL soon :)
———————————————————————————
Week 15 - Wrapping things up and 2 side COLL recognition
Goal:
Sub 17/8 on F2L
Instantaneous COLL recognition
Comment: Finished off the ‘going round steps‘ thing now :)
———————————————————————————
Week 16 - Competition practise
Goal: sub 20
Comment: Since I’m going to a completion in less than two weeks now, I’m not going to try anything new for the next two weeks, just going to do lots of timed solving.
———————————————————————————
Week 17 - Competition practise
Goal: sub 20
Comment: sub 21 now, maybe I’ll get to sub 20 with some practise before comp. I’m going to start T ZBLLs this week.
———————————————————————————
Week 18 - Planning out 2x2x2 and learning SS T ZBLLs
Goal: Sub 20
Learn last few ZBLLs for the first subset of T
Plan out 2x2x2 every time
Comment: ZBLL started! I’ll do a couple algorithms per day, and drill what I know already along with that. Hopefully, this week, I’ll push to the sub 20 barrier and be able to call myself sub 20 with Petrus (faster than Lars now :)).
———————————————————————————
Week 19 - Drilling Last Layer algs + training SS T ZBLLs
Goal: Every COLL, PLL and ZBLL alg I know, to be sub 2, preferably sub 1.75 with some. SS T ZBLL recognition to be two sided, and almost instant.
Comments: So just some alg spamming, last layer scrambles, and yeah.
———————————————————————————
Week 20 - 2x2x2 efficiency + learning SO T ZBLLs
Goals:
-2x2x2 7 moves or under
-One looking it
-Inspection time to look for as many possibilities as I can
-12 algorithms learnt
Comments: So yeah, I’m going to work on my block efficiency, do slow solving, and also try looking at as many different corners to build the 2x2x2 around as possible in inspection.
———————————————————————————
Week 21 - 2x2x3 efficiency + drilling SO T ZBLLs
Goals:
- 2x2x3 15 moves or under
- Trying to find expansion corner in inspection
- 12 algorithms learnt
Comments: Being lazy with algorithms as usual, need to pick up the slack. I thought it
would be a good idea to expand my inspection capabilities further, so I
set this goal.
———————————————————————————
Week 22 - Break from speedsolving, doing BLD
Goals: Learn full M2, be sub 5 mins
Comments: So, I wanted to try something new for a bit, since if I just keep practising 3x3 speedsolving forever, I will go crazy. BLD seemed like a challenging option, so I went for it. I managed a couple of successes a while back before this thread was even created, but gave up a while afterwards, so at least I won’t be diving in with no knowledge at all.
———————————————————————————
Week 23 - 2x2x2 to 2x2x3 transitioning and LS recognition
Goals:
Sub 4 expansion
No unnecessary AUFs in LS
Comment: So hopefully, this week I will push my lookahead and inspection to the limit, and finally have a decent expansion time. When I finish that, I’ll also look into recognising LS cases better, since I frequently AUF to find the orientation on pieces and things.
———————————————————————————
Week 24 - 2 gen F2L
Goals:
Sub 4.3 F2L
Comment: My two gen blockbuilding tricks could be better, at the moment I do it pretty similar to 2x2x3, individually solving a pair, then connecting it with an edge. I need to pay more attention to where all 3 pieces for the 2x2x1 are before continuing, hopefully I’ll be able to do that during EO. And of course, my TPS could be way better here.
———————————————————————————
Week 25 - Individual steps
Goals:
Sub 4 expansion
Sub 4.4 F2L
Sub 4.2 Last Layer
Comment: It’s a long shot to be able to do this by the end of the week, but I’ll probably give it another week, and hey, maybe I’ll do it, and move onto 2x2x2 and EO.
———————————————————————————
Week 26 - Individual steps
Goals:
Sub 4 expansion
Sub 4.4 F2L
Sub 4.2 LL
Comment: Didn’t so much last week, was slightly ill, I hope to finish off this week :)
———————————————————————————
Week 27- Taking a break
Goals: Not much
Comments: I hope to do some more 4x4 this week, I’m sub 2 min now :)
———————————————————————————
Week 28 - Individual steps continued
Goals:
Sub 4 expansion
Sub 4.4 F2L
Sub 4.2 LL
Comment: I think I’ve got the 2x2x3 now, F2L needs a bit of work most of all. I’ll so some splits today probably.
———————————————————————————
Week 29 - Drilling new techniques + ZBLL
Goals:
Sub 15 average
Half of T set done
Comment: This week will mainly be solves, I’m doing pretty well with my previous goals, and I’m almost sub 15 right now, so I thought I should give myself a chance to stop learning new things and focus on practising what I already know. I haven’t really been learning ZBLL recently, I know a miserable 3/2 of a T subset so far (around 20 algs), along with COLL and PLL.
———————————————————————————
Week 30 - Working on planning 2x2x3 in inspection
Goals:
Be able to see one piece of the expansion in inspection
Comments: In the long run, this will really help with 2x2x3 speed, and it’s definitely going to be needed - it’s basically the equivalent of seeing an X Cross in inspection.
———————————————————————————
Week 31 - Taking a break
Comments: Haven’t been practising much lately, so I’m just going to take a break then get back into it.
————————————————————————————
Week 32 - Drilling F2L
Goal: Sub 4 F2L
Comments: Did some splits last week, concluded my F2L was one of my weaker points. Going to try some 2 gen scrambles.
————————————————————————————
Week 33 - Drilling F2L
Goal: Sub 4 F2L
Comments: Was pretty lazy last week, still need to work on F2L ;)
————————————————————————————
Week 34 - Expansion lookahead
Goal: Sub 4.75 2x2x3
Comment: My blockbuilding is OK once I find the pieces, but generally I take a while to find them, so hopefully I can work on that. I’ll also look into more inspection usage.
————————————————————————————
Week 35 - Expansion lookahead + ZBLL again
Goal: sub 4.75 expansion
Finish learning second T set
Comment: I’m a lazy boi :p
————————————————————————————
Week 36 - Break from 3x3, doing some side events.
Comment: B Day a few days back, I got a Square 1 and 2x2, waiting on a Megaminx too :)
————————————————————————————
Week 37 - Doing some splits, continuing work on 2x2x3
Goals:
Break sub 13.5
Learn a few more ZBLLs
Comments: Back, doing splits right now, hopefully they’ll be better than last time ;) I need to start practising more to be honest.
———————————————————————————
Week 38 - Going back to the old tutorials and lar5.com
Comment: I haven’t really learnt any new techniques in ages, and my blockbuilding style is still quite similar to when I was averaging over 20. I need to go back to the basics, perfect everything.

———————————————————————————
Week 45 - Just some solving
Goal: Sub 13
Comment: Been getting consistent 12s and 11s recently. I think I’ll break sub 13 at last soon
———————————————————————————
Week 46 - More solves, and ZBLL restart
Goal: Sub 12?????
Actually learn some ZBLL
Comments: Sub 12 seems kind of far fetched considering how long it took to go sub 13 but bigger goals tend to motivate more. And I feel like I really need to actually start grinding away at ZBLL - it’s been put off for too long.
———————————————————————————
Week 47 - Splits and ZBLL
Goal: 2 T sets of ZBLL done
Try for sub 12
Comment: Refreshed my old algs and memory last week for ZBLL, didn’t get much improvement out of grinding solves then. Will do some splits to practise individual areas
Sub 13 with Petrus now!
Ao5 PB currently 11.391
Hopefully you are ok with it so that's why im asking. Is it ok if I do the same thing with corners first?
