I just noticed that badphemisto actually has several E-perm algs.

On his "2-look PLL cheatsheet", it says x' [ ( R U' R') D ( R U R') ] u 2 [ ( R' U R ) D ( R' U' R ) ].

THAT's the one I can't stand.

On some youtube video, I found this one : z U2 R2 F (R U R' U')3 F' R2 U2 z'.

THAT's the one that I find slower than two A-perms.

However, on badmephisto's regular PLL page, it says : x' (R U' R') D (R U R') D' (R U R') D (R U' R') D'.

NOW this one is great. MUCH faster than two A-perms. In fact it's nearly as fast as a single A-perm.

A special thanks to @One Wheel for pointing out the existence of cyotheking's video, where he uses this last alg.

Wow, those first two really are bad. I also figured out another one by replacing cube rotations with wide turns in another existing alg. I don't remember the whole thing, but it started out with Rw U R' U'. Once I figured out the left ring finger thing that last one is good enough for me.

That is the Rowe E perm.

I have no idea. The opportunity for timed solves is so hard to come by that I've never looked at splits. If I get a chance I'll have a look at the videos from North London

Definitely recommended. Memo is as significant as execution time and getting faster at 3BLD demands training your memo to be fast. Try to rush memo and you'll see an instant dramatic drop in your times (although maybe accuracy too ).

FYI, when I was about 3:30 I measured splits and found my memo took about two-thirds of the solve. That's a looong time. Plus pauses in execution due to memo being weak. So I worked on it separately and made rapid improvements, and that's really the main thing I did to get sub-2. Now my splits are about 40 secs/50 secs and I do more memo than execution training. I can show you my memo training next weekend if you're interested.

Fast solvers spend about one third on memo. I have a long way to go before I can memo in 7 seconds like Kaijun Lin though .

 

[h2f]

Yes, memo is the part of bld solving which is much more important than execution. I mean - one's time are up of one's memo more than up of execution.

@teacher77 If you look at regular Eperm you can see that it's made of 2 OLLs:
x' (R U' R') D (R U R') D' (R U R') D (R U' R') D'.
The first part is the first OLL: x' (R U' R') D (R U R') D'. And it's pure comm. Do it twice and you will see tha case it solves.
Second part is the second OLL x' (R U R') D (R U' R') D'. Again pure comm and done twice prepares the case it solves. Now you know Eperm and two OLL's.

Oh thanks ! But does are two of the 2-look OLLs so I knew those cases already. Nice to know a new alg to do them though !

 

[teacher77]

At least, here's a vid of one of my solves. The angle isn't great but that's what I could manage with a simple cell phone. I hope it will be useful for a critique :

(oh : 0-0:19 is the shuffle, then 0:19-0:33 is the inspection)

Thanks !

Ok ... started looking more proactively at Hoya. Have done a few slow solves just trying to get my head around what I can and can't move particularly when doing the Hoya cross. Going to spend some more time later today doing more solves. Hopefully I can start speeding up at a point to really put it to the test.

Did some timed solves last night using Hoya. After an ao12 my average was around 15 seconds slower using Hoya which i suppose is not bad. Hoya does seem shorter and I'm always surprised when I get to the L8E's. Going to pres on and see if I can get my times lower.

I'm only now getting to my Yau times in Hoya after several weeks but I don't practice much. I did look to go back to Yau but realised that I really don't like it as much. Trying to find 2 cross edges at a time rather than one was the deciding factor. I'd hoped to get to cut off times by the competition next weekend but that's not going to happen.

I did a few Yau solves after doing some Hoya. The Yau solves were faster but I knew that would happen anyway as I have that process down and know what to look for. With Hoya I can see the potential to get faster. For now I am going to stick with it and see how it goes.

Thanks, this is great advice ! What source are you using for algs ? I use the ones on badmephisto's site (except the Eperm, which I can't stand). Do you recommend them ?

The best place to look for algs is http://algdb.net/ . It has probably been mentioned already but Cyotheking has some some cool video tutorials on the PLL's which is well worth checking out.

I used pretty much entirely bad mephisto's cheat sheet for OLL and PLL. I think the only one I changed was the N Perm that the guys here told me about.

I also used Badmephisto's alg sheets when initially learning PLL's. I've since changed some of the algs he uses to something more comfortable for me. When it came to OLL's I made my own spreadsheets with the algs as a way to learn the algs. Splitting them up in similar shapes. That spreadsheet has grown to include all the algs I use including all the OH algs some of which I still need to learn.

 

[h2f]

Oh thanks ! But does are two of the 2-look OLLs so I knew those cases already. Nice to know a new alg to do them though !

I thought so, you know other algs.

Nice solve. I think the first thing you need to improve is the cross on the bottom. When you used to you will see significant improvement. Your f2l at this stage seems decent as well as 4 look LL. I can see the OLL I mentioned on the video - that's the one I thought you use.

 

[JanW]

Nice solve @teacher77! I agree with h2f, solving the cross at the bottom might be more difficult at first, but it will pay off.

You take some time recognizing the U perm at the end. First you AUF to have the bar at the back, then look at all 4 sides. U perm is best recognized if you think in terms of opposite colors. When you do the last moves of the A perm, you see a green bar on the left and red orange on the front. Since red and orange are opposite colors, you know the edge has to go to the opposite side of the cube -> it's a clockwise U perm. If you have a bar on the left and two non opposite colors on the front, you know the edge from the front has to go to the right -> it's a counterclockwise U perm. With bar on the right it's the other way around, opposite in front -> counterclockwise, non opposite in front -> clockwise. Try to get used to determining the direction of the U perm just by looking at one side in addition to the bar.

BTW - 40 seconds averages after almost 3 months of cubing is a very good result. I was 40 after a half of year or something.

 

[newtonbase]

That is the Rowe E perm.

I've just had a go at timed, fast solves with splits.
1. Kept making errors. Gave up after 4 mins. Realised I had wrong orientation. Restarted with 2:06 memo. Quit one pair into solve as memo had gone.
2. Painful memo. Forgot to time split but at least 4 mins. Awful solve out by 5 edges and an F2. 5:13.
3. 1:41 memo. Lost track of memo halfway through edges.

Seems my memo may need a little work.

I'll take you up on your offer at the weekend @mark49152

Which alg do you call the "standard" alg for Eperm ?

Hello. I recorded my execution of the standard E-perm a few weeks ago. It was ~1.2s even with my "older cuber" fingers:

Edit: This is the "standard" alg popularised by Rowe Hessler and what you'll see in Chris Olson's video.

I had the same G perm 4 times in a row (twice in the 1:30 solve). Got it right the first 2 times.
Don't think my head is in the right place today.

After 4-5 days off the forum and off cubing here I come again
Definitely liking the SS Aurora Mega more and more. It's like I wanted a modded SS to feel but without having to mod it Qiyi Galaxy off my "to buy" list almost surely... for now

Got a nice PB single and Ao5:
Single: 2:43.61, finally sub-3 min! My old PB was 3:02.xx
Ao5: 3:13.43, old one was 3:32.xx

This was after disappointing Ao5 for the weekly comp that, at least, served as warmup

Lots of activity as always during the days I've been off. Nice E-perm video Michael @Logiqx and welcome @teacher77, you will improve soon if you keep practising. Not much else to recommend to what has already been said by others. Definitely change to cross on bottom, try to plan the whole cross (or at least 3 edges) during inspection and try to avoid cube rotations during F2L if possible. Practise slow untimed solves until you can intuitively do most F2L insertion cases not only on the front slots but also on the back ones and, at least as soon as you are inserting one pair start looking for the next one (later on you will be able to do it during the whole pairing-insertion phase).

First mbld attempt in about a week, 2/3. However, time was 13.56 (8min memo, sub 6 execution) which is about twice as fast as my attempts last week. I've done >50 single bld solves since my last mbld attempt, which clearly payed off.

My fastest 3bld success last week was 2.53. That's still quite a lot slower than my pb from last fall. Back then I was doing memo sub 1 min, now my fastest memo was about 1:20. I really need to finish and learn my word list. I spend most of memo time trying to come up with words.

 

[newtonbase]

A few more 3BLD attempts has shown that I'm 2 parts memo to one part execution.

Anki is good for that... once you have a list.

That's good news in a way, as it means you can improve your times easily with a bit of work on your memo .

Thanks, hadn't heard about that software. Looks like a great tool!

Not sure if this has been posted in this thread, but I have found this app a huge help with blind training ... https://www.speedsolving.com/forum/threads/bldtrainer-new-application-for-practicing-3-cycles.61303/

My memo still sucks and have started to establish a proper letter pair word list.

Thanks, I'm glad you enjoy my app! And glad to hear it is being used. I should practice with it more myself as well.

Yes it was mentioned. I'm big fun of this tool, @JanW.
