Mats, how fast is your BLD execution? You're almost better off doing sighted BLD for small cubes :P

You are not the first one to note my slow execution, I'm about the slowest turner
on the circuit :). So exec bld is normally 1:00 (fast) to 1:20 (slow if without memo recall).

I just did this weeks Multi (7/8) and noted that the exec of 8 cubes multi took a little less
that 12 minutes. That is not so much slower that the aces in Multi, only 30-50 % slower
or so. I don't memo fast enough for a really good Multi. I'm still the oldest Multi-er in the world :).

When you compete, the rest of us realize how far we have to go. :( But I love it - thanks for competing this week - it's nice to see how it's done!

No worries Mats, we all have good weeks and bad weeks. Next week will be better!

Ville, I really wonder sometimes if you're doing the same things the rest of us are but SO much faster, or if you've somehow optimized your method to the point that it became a much better method than what everyone else is using. Absolutely incredible!

Did you see his post where he describes how he does it? (Please note that, although he gives a scramble that is written for slice turns, he does wide turns instead of slice turns when applying the scramble - I don't think I ever mentioned it on that thread, but the scramble won't make sense unless you do that!) His method is extremely optimal, but nothing earth-shattering. The most impressive difference between him and us is probably the place where he says "now it gets pro", but I can't imagine that would save more than 10 or 15 seconds on the whole solve. Other than that, here are the differences I notice between him and me. I even use lots of the same algorithms he does - more than half of his algs are either the same as mine or a cube rotation away from the same ones. Many of them aren't even differences between him and you - I think you're closer to his style than I am.

1. He uses supercube-safe algs for central edges, so he can solve them first. I suspect switching to this would help me a little bit, since most of my algs are also supercube-safe - my problem is that I don't know which ones aren't, so I can't switch until I take the time to figure it out. I doubt I'd save more than 5 or 10 seconds by switching, though - it would just make my solve flow a little better.
2. He never breaks a new cycle - he always finishes one cycle with a 2-cycle and then starts a new one in place. For centers, I will break a new cycle if I have a 2-cycle at the end of one, but I won't break a new cycle if I have a 3-cycle at the end of the previous one. I think this is very different from you - you always break a new cycle, right? So he's getting as much benefit out of me as I'm getting out of you. Since he uses either visual or letters for memo, it's no problem at all for him to do many short cycles instead of one big one.
3. He doesn't break cycles with wings, and I do. I think you've said you do this his way, though. I think your descriptions of how you do wings seem awfully similar to his, other than the "now it gets pro" thing.
4. He uses lots of r and l slice turns in his algs - almost all of his commutators are performed with middle slice turns as r or l. He almost never does u, d, f, b, E, or S turns. I've done a lot to try to minimize mine, but he's really pro at this. I figure this is probably the biggest difference between his approach and mine - it might make as much as 30 seconds difference on a solve if I would switch; I may try to figure out if I can find ways to switch to doing more of these kinds of algs.
5. Of course, there's the "now it gets pro" thing - it would be really nice to learn to do that - I may have to try.

So anyway, I think if I switched to his exact method and got really comfortable with it, it would probably drop me from my current 15 minute average down to about, oh, say, 13 minutes. The rest is just amazingness, I think. Ville is amazing.

A little big bld redemption: (and thanks for the encouragement :))

5x5: 20:35, 18:15, dnf (not so good), dnf (2 wing edges), 21:15 = dnf
2+3+4+5: 43:50.11 which is PB with 2 minutes (memo 27-28 min)

@okayama: nice 4x4, you do make progress all the time!
 
3x3x3BLD: 2:41.26, 2:03.91, DNF
comment: done using riffz's suggestion of using my auditory memory method for edges, and my image memory method for corners.
4x4x4BLD: 7:00.41, 6:45.20, 6:18.14
5x5x5BLD: DNF, 16:35.79, 15:50.46 (10:25)
comment: auditory central edges and image corners. I very rarely look at what my memorization time is on 4x4 or 5x5, but I happened to catch a glimpse on the 3rd solve.

Done BLD:

3x3x3: 1:31.64, DNF, DNF, 3:37.71, DNF = DNF
comment: auditory edges, image corners
4x4x4: 7:00.15, 7:03.29, (7:30.44), (6:10.58), 6:41.83 = 6:55.09
5x5x5: DNF, 14:46.12, DNF, 15:12.03, 11:29.07 = DNF
comment: Auditory central edges and image corners. 11:29.07 is my new pb solve!
 
Mike Hughey:

My non-BLD event of the week:
7x7x7: 7:57.41, 7:39.11, 7:29.66, 7:16.31, 7:32.11 = 7:33.63
Comment: Pretty average for me, I guess. I was around 3:30 on centers, which is a little faster than usual, which must mean my edge pairing was a little slower than usual.

The BLD events:
2x2x2 BLD: 20.97, 18.53, 27.81 = 18.53
Comment: Wow, those were nice scrambles – especially the second one!
3x3x3 BLD: 1:37.03 [1:35.03 + 2], 1:38.50, 1:42.03 = 1:37.03
Comment: The first one was off by a D2 – I have no idea why. Fortunately, it still counts!
4x4x4 BLD: DNF [7:50.71, 3:37], 6:34.71 [3:34], DNF [6:52.15, 3:43] = 6:34.71
Comment: First one off by 3 corners (executed OU backwards) and 2 wings (memorized a letter twice in succession: CS, SE – somehow I forgot that I had already memorized it). Third one was off by 3 wings (I memorized KI as kite, when it’s supposed to be Kia (a car), but then when I executed, I treated kite as KT (which is what kite is supposed to be)).
5x5x5 BLD: DNF [14:38.00, 7:07], DNF [14:41.32, 7:58], DNF [16:39.30, 10:24] = DNF
Comment: Ugh. I’m joining Mats with a bad big BLD week this week. I’m just happy it happened in the weekly competition instead of at Dayton. :D Times were not bad, but I missed them all. First one was off by 3 wings (memorized and recalled properly, but executed the pair in the wrong direction). Second one was off by 3 X centers (memorized L as T so I had 2 T’s) and 2 centrals (I didn’t see a flipped edge because it was surrounded by matching + center colors, so it fooled me into thinking it was oriented correctly). Third one was off by 2 + centers ( memorized W instead of X) and 3 centrals (executed NP as PN, even though I recalled it correctly).
3x3x3 multiBLD: 2/3 = 1 point, 9:45.67 [5:19]
Comment: First cube was completely scrambled because I misoriented the cube when trying to flip two edges early, and then I couldn’t remember how I was supposed to be holding the cube. Obviously, I was holding it wrong.

And non-BLD events done BLD:
2x2x2: 22.72, 34.66, 29.22, 34.55, 23.66 = 29.14
3x3x3: 1:38.66, 2:29.31, 1:32.21, 2:29.47, 1:51.66 = 1:59.87
Magic: 11.65, 10.56, 11.06, 10.77, 10.33 = 10.80
Comment: OHITABLD, of course. Nice and consistent this week.
Master Magic: 4.21, 4.16, 4.80, 4.22, 4.05 = 4.20
Clock: 2:39.84 [0:34], 2:11.83 [0:28], 2:07.05 [0:26], 2:15.61 [0:29], 2:46.97 [0:22] = 2:22.43
Comment: Big memory recall pause on the last one – it was really an easy one – might have been a PB without that pause.
Pyraminx: 1:09.66, 58.88, 1:14.88, 1:06.44, 1:16.86 = 1:10.33
Square-1: 4:54.82 [3:23], DNF [5:26.23, 3:07], 5:43.27 [3:29], DNF [6:15.42, 3:30], 4:26.36 [2:37] = DNF
Comment: Ugh, awful. Second one was off by 4 edges (I memorized them wrong); fourth one was really bad because I messed up a corner algorithm (which I knew was wrong because the middle slice was wrong when I was done with it!).

Mike no worries, you had a very good showing at Dayton, as well as your four cube 4x4multi afterward on little sleep! It does seem that we are making fairly similar errors in our DNFs. When you execute the cycles in the wrong direction, do you find that you execute the easier of the two directions? I tend to do this when I cycle in the wrong direction because the incorrect direction is actually easier to execute than the true direction.

Mike, I have noticed that your philosophy of always doing post mortems if helping me. I find that I still make the same errors, but I tend to catch them either as they are happening, or just afterward. For example, I am still making the same mistakes as you describe here, but I realize it either mid execution, or before moving onto the next cycle. This makes it possible to correct it before moving on. I wonder if approaching 100% accuracy does not mean not making mistakes at all, but rather having the ability to catch those mistakes before the end of the solve and correct them.

What are your thoughts on this, as you have been doing post mortems much longer than I have?
