Blindsolving Accomplishment Thread

Oh Dear God, that's just unbelievable. Seriously, man, you're just awesome :o. Congrats like a million times, way to go....Incredible :).

I have a question for you about 5x5 and larger cubes blind. When you were just starting on 5x5 blind, did you get any DNF's because you accidentally turned the wrong slice? I DNFed the first two solves on the weekly contest and they were quite far off, but I was sure my memo was right or at least extremely close to right, so I figured it must be a wrong turn on execution. That's what I'm most nervous I'll mess up on the 7x7, that I'll accidentally turn the wrong slice. (Because there are quite a lot of them on the 7x7.) Any way to help this besides just being careful and making sure you have the right one?

I really haven't had much problems with it, actually. I might have had a few 5x5x5 DNFs due to this (and I probably still occasionally do), but not enough that I really noticed it much. Although after analyzing my first 7x7x7 attempt (the DNF) some more, I decided that in addition to not doing an R' setup move undo, I must have done this once - I turned the wrong slice one time (third instead of second, or vice versa). It left me with 2 sets of strips of unsolved centers that accounted for many of my bad pieces.

But I think I've decided that it seems like the best thing to do is just not to worry about it too much. I think that's why my time was as good as it was. I just went for it like it was a regular 4x4x4 or 5x5x5 solve. When you're doing outer or inner + or X centers, it's nice because you're always turning the same class of inner or outer slices. So they're kind of easy. And r2 REALLY helps for bigger cubes for the wings, because you're always either turning outer faces or the particular r2 that goes with the set of wings you're working on. I think r2 becomes a bigger and bigger win as you get to bigger and bigger cubes.

The obliques are the hardest ones. But after a while you get used to the idea that one class of commutator moves always moves the third slice and another class always moves the second slice, and then it becomes rather comfortable (as you get used to which class each move belongs to). I really think some practice will make a big difference in the speed of doing obliques. I must admit that I did do a fair amount of counting slices while doing the obliques.

Anyway, I think the reason I was successful was really because I didn't worry about it too much. I was careful, but not enough to let it really slow me down much. And I think that helps.

And I'd like to say once again thank you everyone for the congratulations. It's nice to see all the kind comments!

You deserve them all mike! :D
and if you Try 7 MultiBLD please GOD get that on video! :D :D :D :D :D :D

7 multiBLD on video is an interesting challenge. All I have is a miniDV recorder (maximum of 90 minutes with the lower resolution). If I ever record a 7x7x7 BLD, I figure I'll just record the solving phase, since the memorization phase would make it too long. A 7x7x7 multi? How can I fit that on a tape?
 
Practiced for 7x7 blind by doing a 5x5, two 4x4's, a 3x3, and a 2x2, which is more than one 7x7 I think. Memo was actually a lot easier than I thought. The result was I was off by one 4x4 and the 5x5. The 5x5 was off by three central edges. The 4x4 was off by several "lines" of centers and wings, which makes me think I forgot a slice turn or something. Total time was 1:21. Memo was 51 minutes.
 
Hmm... looking at the number of pieces. You take 1 5x5, 1 4x4 (- corners), and then add 24*3 for the oblique and outer T centers. Since a 4x4 is 24*2 + corners, you end up getting very close with just 2 4x4s and a 5x5. Your estimate was very close :) I don't think I will end up DNFing a 7x7 BLD because of execution, but I obviously can't memo if my life depended on it. Maybe I should really try a 5x5...

Very nice, Alex.

I scrambled wrong :/ But I recreated the solve I got using ACube. It has 3 corners placed, so kinda lucky.

I wouldn't say 3 corners permuted is lucky. I'll try this scramble.

o_O

I call every solve which has less than 19 pieces to memorize lucky.
 
On Joey's scramble: 1:05 DNF

@tim
Umm, so lucky solves happen all the time for you? Think about this. Do lucky solves happen on speedsolving as often as you have one piece solved on a scramble? Of course not. Therefore, a lucky blindsolve should be something that doesn't happen that often. I consider a lucky blindsolve to be one where 20% or more of the cube is done. So on a 3x3 >4 pieces solved, which doesn't happen very often.

20% is a somewhat silly thing to say.
I'm tooo lazy to find the chances for >4 from http://cube.garron.us/BLD/probabilities.htm, though.

But please also don't forget how tim memos.
