On the forth scramble there was a 2x2x2 block already done, that's why it's so good.
BUT, I scrambled wrong. Now I'm not sure whether it's valid?!

Don't click show if you're planning on FMC this week :p Don't want to spoil it.

Grey is cancellation.
Then used Niklas to solve LL in place.
R B' L' F2 U2 R' U R U L' D' L U F' D' F U2 D R D' R' B' D F D' B D F'

Damn, my best, but we tied. I actually tried with R2 as a premove before inverse scramble, but I didn't find much after that :(
I'd to see what others get on this scramble. Nice and blocky :)
I don't get how you "fmc pros" consistently get sub 30. This is my first sub 30. I just don't see the things you guys do. Insertions usually save me one move at most, and that's when I force a 3 corner cycle. Otherwise, it's more efficient without insertions :(
Hopefully I'll improve, I get to do FMC in November, and that may be my only chance for a long time, so I don't want to mess up. Hopefully I'll be better by then :)

FMC: 28 HTM

Solution: R2 U' R U2 B F2 R B' D B D R L' F L R2 D' L D' d' R2 d R2 D2 L' D R' D

2x2x2: R2 U' R U2 B
2x2x3: F2 R B' D B
F2L+EO: D R L' F L R2 D2 R
LL: R' D L D' d' R2 d R2 D2 L' D R' D (3 moves cancelled)

This was my backup solution, which I happened to find almost linearly. Too bad I couldn't find anything better for this nice looking scramble.
 
Mike Hughey:

My non-BLD event of the week:
Master Magic: 3.36, 3.18, 3.47, 3.21, 4.56 = 3.35
Comment: Wow! All of a sudden, I could go faster. This is something like a half second faster than I've ever done before, I think. Maybe all that BLD practice paid off. :)

The BLD events:
2x2x2 BLD: 23.05, 21.25, 34.02 = 21.25
Comment: Nice.
3x3x3 BLD: 1:59.47, 1:28.08, DNF = 1:28.08
Comment: Second one was really hard - I'm surprised it was so fast. Third one I couldn't remember the last pair.

And non-BLD events done BLD:
2x2x2: 31.31, 28.25, 38.52, 28.16, 34.13 = 31.23
3x3x3: DNF [1:32.56], 1:45.84, 1:57.88, 1:55.05, 3:41.69 = 2:31.54
Comment: Well, the last one ruined the average time, but at least I got an average! Very big memory pause on the last one.
3x3x3 One Handed: 2:55.05, DNF [3:05.36], 2:46.66, DNF [7:09.43], DNF [2:51.97] = DNF
Comment: Pretty bad. Second one was off by 3 edges and 2 corners; fifth one was off by just 2 flipped edges; fourth one I couldn't remember the last set of edges, but I struggled with it for a long time because I didn't want to fail the average. Oh well.
Magic: 10.47, 10.13, 10.77, 11.30, 8.50 = 10.46
Comment: OHITABLD, of course. Wow! I'm getting faster. And check out that single - almost a Stachu kind of time there! :)
Clock: 2:54.16 [0:45], 2:51.34 [0:31], 2:44.83 [0:35], DNF [3:13.65, 0:27], 2:17.44 [0:24] = 2:50.11
Comment: DNF had one corner off by 2.
Pyraminx: DNF [1:44.18], 55.69, 1:06.19, 1:34.68, 1:36.55 = 1:25.81
Comment: First one off by 3 edges - I cycled them backwards.
Square-1: 8:22.09 [4:20], DNF, DNF [9:51.38, 4:38], DNF [7:42.72, 4:49], 12:06.08 [6:04] = DNF
Comment: At least the first one was pretty good. First solve: shape OP, edge parity; I did it on the stackmat without a stopwatch backup by accident - luckily, I got it in time! Second solve: shape GC - I don't have it memorized yet. Third solve: shape NS, mismemorized, off by 3 cycle of edges. Fourth solve: shape KB, mismemorized, off by just 2 edges. Fifth solve: shape VV, edge parity; had trouble remembering the matrix for the case, but I eventually got it; took several minutes getting to square after pulling on the blindfold.

All done BLD
6x6x6: 47:13.38 DNF DNF DNF 39:16.62 = DNF
7x7x7: DNF 1:10:49.61 DNF DNF DNF = DNF

Comment: I told myself that I would practice all the 6x6 and 7x7 BLD solves this week in order to better train my 5x5 for next week. I'm not making any promises about my 5x5 performance next week, but I do definitely feel that all this bigger cube BLD practice will certainly help me for my memorization, and being better able to not review before starting the solve.

Almost all of the DNFs solves were really close, and I was able to trace the problem down to one or two errors: either a commutator error by doing BAB'A'B or by memorizing the wrong piece during memorization. On the third 7x7x7 solve I memorized too quickly and had a serious memory recall issue on the right obliques (the last center orbit that I memorize). I must have spent well over 20 minutes trying to logic through the available pieces and remember what I memorized, but I wasn't able to. Other than that solve I didn't have a solve that had more than 3 errors I'm pretty sure, so I'm happy about that!

Memorization time for the 6x6x6 was usually around 24 minutes or so, but I memorized in 17:05 for the 39 minute solve. For the 7x7x7 my first solves I was memorizing around 35 minutes to be safe, but I started going faster and taking more chances on the last 3 and was memorizing in around 28 minutes on average.

My brain feels like total mush. I feel like I've trained to the point of absolute failure and then some. What's exciting, though, is that on the last two 7x7x7 solves I was able to memorize through the end of all the centers without pausing to review at any point during the process. On the last solve I reviewed anyway, but only once quickly through centers when I finished memorizing them, and once through edges after I finished memorizing them too.

Although my focus is 4x4BLD and 5x5BLD, I will definitely keep practicing the bigger cubes at least a little in the future. It is absolutely thrilling to get a bigger cube BLD successfully! I don't really get that excited anymore about a 4x4 or 5x5 success, only a good time. I still fist pump and shout "yes!" whenever I get a bigger cube successfully though! :)

Many thanks to Mike, Mats, Istvan, Maarten and the others doing bigger cube BLD. It's inspirational to see how you guys practice, and from what I've heard this practice helps for BLD on the medium cubes as well, which I hope is the case.

Chris
 
Wow, nice job, Chris! It looks like your accuracy on bigger cubes BLD is very similar to mine, and your times are getting close to mine too - especially memorization time. I hope it helps your 5x5x5; I'm looking forward to seeing how your next few weeks go.

Interesting that you make the mistake of doing BAB'A'B. I almost never do that. I will sometimes do BAB'A or BA'B'A', but doing BAB'A'B? I'm not sure I've ever caught myself doing that. Perhaps it comes from my former practice of counting the moves for commutators. I usually don't explicitly count anymore, but I still hear the "beats" of the count. If it's odd, I know I've done something wrong, so the only way I'd do this would be if B were an even number of moves (which is not so common, at least for me). Memorizing the wrong piece, on the other hand, is a very common problem for me.

Oh, and I'm going to start doing big cubes BLD next week, after my first ever 3 week break (edit: whoa! it's almost been 4 weeks!). It will be interesting to see how that affects my times - I'm curious if the rustiness or the freshness of the memory rooms will prevail.

Invert the whole thing!

Strange, everybody got 28 moves this week ;-)!

All done BLD
6x6x6: 47:13.38 DNF DNF DNF 39:16.62 = DNF
7x7x7: DNF 1:10:49.61 DNF DNF DNF = DNF

It's fun to read about your experiences now. I particularly agree on two things.
  • The feeling to see one solved. That's awesome.
  • The ease with which one can memo a lesser cube after practicing big ones.
 
2x2 BLD: DNF, DNF, 37.81 = 37.81
4x4 BLD: DNF [12:10 (including a 2 min recall delay), 4:20]
5x5 BLD: DNF [26:50, 12, 6 +-centers]
ugh, I hate being close... memo actually could've been several minutes faster had I not screwed up on +-centers memo (don't think that the memo was the problem though, probably an exec mistake). Still, it's always nice to not screw up anything else :).

dude signature is 3x3: Single:16.20, Avg of 5:18.78, Avg of 12:19.83

what`s happen ?????????????

This thing happened where I dont beat my PB every avg I do. Longer explanation: On the 28 I put cross pieces in wrong and didnt realise and the 24 was just slow.
