Thank you! And congrats everyone. It's funny because my big cubes were the thing I was less proud about I don't know how to finish the cubes in FMC

You might not be proud but the times were really good. Not that your 2x2 and 3x3 times were not good but there are so many fast people at those events in the forum that even for you it's gonna be tough to win at those.

Thanks, for kind words. You will see that doing a lot events pays back but it takes time. I had same feeling when in last year I've started to make a lot events in WC.

My solutions in FMC are based on the scheme: make 2x2x2 (or 2x2x1) first, expand it to 2x2x3, do EO, do f2l-1, put last edge prepare insertions. Up to the solution I make sometimes this stages look different. I prefer doing 3 corners than 5 corners even if the skeleton is longer. Thats all. In last solve I did like that. I've noticed that with white on bottom there's a lot of pairs. So z2 rotation. Next I've noticed easy 2x2x2. So I tried to add random move before block to see what happens. I tried L2, L' and L. This trick Marcin Stachura made in 2014 when he made NR. Thats why theres L' before block. The rest of solve is quite obvious. The L' move made me edge in right position to make next 2x2x1, next I've noticed easy pair when puttin 2x2x1. f2l-1 and eo simultanously is a matter of luck. I've finished with 4 corners in two pairs. Durign insertions I try to find move which cancels with move from skeleton. I've find -4 insertion (8 moves insertion but 2 moves cancels with 2 from skeleton). The second should be done in the end but I didnt notice theres fine position to do it. This would give 27. Instead I found isertion with no cancelation. Marcin Stachura told me that I should look for the first insert which cancels 4 or more moves. Sometimes it doesnt happen - I had such solutions. And 4 corners can give a lot of cancelations.

z2 L' //random move
D' R2 F** //2x2x2
B' // pair
U R' B2 R U2 B // 2x2x1 and pair
F' U F // eo f2l-1
L* U L'//ab4c

* L' U R U' L U R' U'
** U2 R' D2 R U2 R' D2 R

alg.cubing.net

If i would do insert in insert it gives: 27
*(L' U R U' L (L' B' L F L' B L F') U R' U') = L' U R U' B' L F L' B L F' U R' U' with cancealtion in the front and in the end.

Cograts Alberto. Awsome score!

there it goes

That's amazing. I might be near on 3x3 PB but you'll be ahead of me in this for many years (probably forever).

The less rotations the better but, in F2L, as edges are not oriented, as in ZZ, there are times where it's faster to rotate than to try and do Fs and Bs, which are not easily finger-trickable. So, I'd say Jason's solve is quite nice and it is not only PB but full step. Well done, Jason! I have to time that one myself

Thanks that's a good description. I'm pretty bad at too many rotations in general but getting better. This one I agree was not bad for me.

David thanks for the alg.cubing link. It's not working on my phone but I'll try on my computer.

Very nice! You do CO and CP quite fast. I tried with the commutator that you use but I was not very fast with it so came back to Niklas. Maybe I should try again.
So we are now tied at best Ao12 Those final 15 seconds are going to prove difficult to cut for me.

 

[mark49152]

I think this may help: https://www.youtube.com/watch?v=M32OkdonaVg

That's pretty much what I would have done intuitively based in 4BLD knowledge but it's nice to see it endorsed by Roman .

On reflection I am going to forget about 6BLD until after next comp. I just spent 40 minutes rescrambling a 5x5 blindfolded so I need to get competent at that first. I'm not even sure I will do 5BLD at the comp. I might just focus on getting a better 4BLD official PB and defer 5BLD until I've done that. There's only 1 hour for both.

 

[h2f]

Ok. I understand it. Luckily I may have comp in April but only with 3bld of blind events.

 

[Jason Green]

Congrats, and reconstruction is also ok, good job!

5 rotations is normal in CFOP?

https://alg.cubing.net/?setup=U_R2_..._R2_F-_R2_B_R- R2_U_R_U_R-_U-_R-_U-_R-_U_R-_U

I made a couple of tweaks, like putting the x2 in the setup, and putting a couple of primes on the double moves. If you run this at 2.1 speed it is almost what my time is (like 15.9 on my stopwatch).

Well, David, you know, I had to upload my own sub-4 Mega solve
It's not as good as yours but watching it I see that there is some room for improvement. Mistakes here and there and long pauses searching for pieces as well.

Best Ao12 = 4:12

 

[muchacho]

Great, nice solve! my potential with my current method looks much worse, I need to change it soon, although my LL looks faster (I'll try to time it, in this solve it was fast, but it's just the first video I've done).

 

[Lid]

Nothing beats a pb! I'm going to try to reconstruct this because it's so easy. I did a few tries and got down to 11.25. The scramble is on this image (I clicked "last" for the pic).

Ok, I don't even know how to do this really, so correct me if I'm wrong.

Scramble - U R2 U R2 U' L2 U' F2 D' F' D U L' D B2 R2 D B2 U2

Inspection - x2 (put white on bottom, blue center in front)
XCross - L2' B y' D2' F D' (solved 1 F2L slot)
2nd Slot - y' R' U' R
3rd Slot - y' U' R U' R' y R U R'
4th Slot - y' R U' R'
OLL (L shape) - R' F R2 B' R2' F' R2 B R'
PLL (Ub) - R2 U R U R' U' R' U' R' U R' + U

Nice solve Jason

Here is my try on that scamble:
z2 R2 F D2 R D' // same Xcross different angle (and also avoids two rotations)
R' U' R // 2nd
U2 R U' R' U R U R' // 3rd
y' U' R U' R2 F R F' // 4th with forced EO
U L' U' L U' L' U L' D' L U L' D L2 U' // COLL with EPLL skip

I don't really have a good camera nor a tripod to make decent videos ...

I've registered for London, as have a couple of you guys, so I need a practice plan. I do a bit of blind every day so 3BLD and multi are covered leaving 2x2, 3x3, 4x4, 5x5 and Pyraminx I don't care about OH. 45 days to practice so maybe 2 lots of 3 days for each event in a rota with a refresher day for everything on the 4th day. I'll then have a few days at the end to work on weaknesses. Sound good or have I wasted 3 good minutes of cubing on a crap plan that I won't stick to?

 

[mark49152]

Just having a plan is good I think. I can share mine, which is different and designed to make best use of my limited practice time.

For each comp I have two focus events, and I don't seriously practise anything else, just do the minimum to not be too rusty. For the focus events I try not to switch too often -maybe once a week so that each gets a few good runs of several days exclusive practice.

I've been doing this for my last four comps and it's the reason I made rapid progress in 3BLD and 5x5. For Exeter, my focus events are 4x4 and 4BLD. For London, undecided and it depends on how it goes at Exeter.

Thanks that's pretty cool to see how you do it, you know a lot more than me.

Do you remember we have a race to sub-1? Finally I'm back to my normal solves: avg of 5: 1:13.08.

Yes, races to 4x4 sub-1 and 4BLD sub-7 I've not been able to do much practice the last 4 days though.

 

[Shaky Hands]

My plan for both the Exeter and London comps:
2x2: I don't practice 2x2 at all and don't even know all the OLL cases of the basic method. It's just something I may as well enter.
3x3: Regular Ao25 solves, aiming to do a few hundred solves per week (outside of commuting, where I probably do several hundred more too.)
4x4: Not much practice at all. I'm comfortably within the Hard Cut but a long way from the Average Cut, so working much more on 5x5.
5x5: Lots of practice, hopefully get in 100+ solves a week (which for me is many hours) in the hope of beating the Hard Cut and registering a time.
Clock: I'll probably do a fair bit of this in the final week, just to firm up my solving process and try to register a full Ao5 at the comp.

I'm sticking with these 5 events for the time being. I can solve Pyraminx with a crib sheet so might enter that one day in the future. I'm more likely to try 3BLD first though.
