25:xx 4x4 BLD DNF.

26 pieces solved, started with 8. First attempt.

Don't give up! Keep trying, I had 8 DNFs before I had my first success Waiting for your post in the accomplishment thread By the way, that's pretty fast for a first attempt I think, at least it's faster than mine...

Thanks for the encouragement! I'll be doing another attempt as soon as I get the time. I've planned on doing it it for the past two nights, but each time something just seems to get in the way...Too bad there's a life outside of cubing.

Mike did 4x4 sleep-delayed BLD :O http://www.speedsolving.com/forum/showthread.php?p=36286&highlight=sleep+delayed#post36286
I wonder if he has the guts to try 7x7 sleep delayed BLD

Well, I had the guts, but I didn't have the goods. But I was REALLY close!

7x7x7 sleep-delayed BLD (for this week's competition), last night and this morning:
DNF (6:59:33.15, 56:20 memorization time, 44:00 solving time)
Off by just 2 outer + centers.

It's really not very hard for me to do this. I just go over the memorization a couple of extra times, and it's all still there for me in the morning when I wake up.

But I'm not sure I really want to try this again.

Aww man, that's so close!
No pressure to try again, the WCA will just ban you if you don't.

edit:
This is joey on tommy's account, I forgot to log off and relogin.

The worst part of it was that the bad pieces were on B and D, so I really thought I had it right at first.

Nice job mike! so close even on 7x7 BLD and delayed
so amazing!

4x4x4 BLD DNF. 22 minutes, off by 4 corners, 6 centers and 3 edges. This was my second attempt. I was sure it would have been solved...very disappointed. I'll get it soon though.

 

[Rubixcubematt]

this morning i tried to do a 3x3 and a 2x2 blindfolded at the same time. grrrrrr i missed it by having two pieces misspermuted on the 2x2, it was so anoying

 

[Jacco]

5x5 BLD DNF (1:18:16.02)
Off by 6 pieces (4 X-Centers, 2 inner edges, 2 corners) and 2 flipped inner edges. It's my second try so far.

 

[waffle=ijm]

2x2-3x3 sleep delayed (about 20hours total since I couldn't do it until after school and practice and homework) took me about 1 hour to recollect everything. Freestyle Corners with classic pochmann edges for 3x3. Classic pochmann corners for 2x2 and I misoriented the last 2 corners. well it was okay for me...not bad. I need to work on my BLD...memo for 3x3 took forever (not just for sleep delayed) 2x2 wasn't that bad though. I WILL TRY AGAIN!

3x3 BLD failure today, resulting in 2 edges flipped.

I was able to figure out exactly where I slipped up by recalling where the edges had moved from. I had memorized the EO as 749 hex (0111 0100 1001) but when I was processing the "4" I was thinking 4th bit (with most significant bit first). So I performed edge flips it like 789 rather than 749 hex.

I am still pleased that everything else about execution was correct.

Congratulations on the near-miss (and congratulations on your recent successes!). These are actually my favorite kind of BLD solves, because if you can remember exactly where you went wrong, you're pretty much guaranteed to learn from that attempt - you probably improve more from these failures than you do from successes.

Yeah I think I need to spend some time figuring out what went wrong on my screwed-up solves as well, instead of just swearing and chucking my blindfold aside I could probably learn a lot...

Thanks Mike! I had another case of just 2 edges flipped several days ago. I think it must have been the same type of problem. Yes, you can't fix a problem until you have an idea what it could be. Another thing I learned, if the cube is totally mangled, then I probably forgot to restore a cube rotation.

FAIL Sep 12 2008: Two out of two 3x3 BLD failures this morning, but both were inspiring.

During my 1st solve, I was not sure about the twist on 2 corners. I guessed. Later, to fix parity, I did a U-perm to change which 2 edges needed swapping, then set up a V-perm, then undid the set up. When I finished and opened my eyes, all was solved except 2 corners were twisted. Grrr.

For my 2nd solve, I again had trouble remembering my corner orientations. For CP I had a 4-cycle, and 2-cycle, and 2 in place. So I set up for E-perm, then unset up. For EP I had two 6-cycles. I set up for a Z-perm... then I did something stupid. I was so sure I could not have gotten this far with accuracy, that I opened my eyes. I was surprised to see everything was correct. I closed them, did the Z-perm, undid the set up. Grrr. In my mind, I consider this a success, even though it would be termed a failure.

FAIL Sep 13 2008: All correctly except 4 corners were twisted wrong. Guess I need to practice CO memorization/execution! I am proud of the solve. CP was two 4-cycles. Used Caltech Maneuver to fix the last 2 pairs. (See cubefreak.net 3OP, algorithm=(RB'R'B)*3). EP was 2-cycle, 6-cycle, 3-cycle, 1 in place. Used Z-perm to fix last 2 pairs.

FAIL Sep 16 2008, 8am: All correct except apparently the last corner 3-cycle was executed the wrong direction.

4x4x4 BLD DNF. Not sure on the time.

I was off by 4 centers, A red and orange switched and a blue and yellow switched. I looked down and thought it was solved. I went through a huge range of emotions in just a few seconds, haha.

Getting closer though.

Don't worry dude, you'll get it soon. Of my first 8 DNFs, I think 6 or 7 of them had only 2 or 3 center pieces swapped (while the rest of the cube was solved). Center pieces are probably the main cause of DNFs for beginners, because of the unfamiliarity I guess... It's somewhat like the cross for CFOP, it's initially the hardest step because there are no algorithms to get you under 7 moves every time, but with a little practice, it easily becomes the easiest step. You'll get past this stage, don't worry

Those are so devastating. For this week's first 6x6x6 BLD, I though I had it for 10 seconds, only to discover a white and yellow center piece were swapped (they're on the right and in the back, in my color scheme). But yeah, just focus on how close you got - but for a tiny bit of bad luck, you would have had this solve!

ive done 2x2 bld before, but never 3x3 bld.

I got a 7.03 DNF on this scramble because of 2 misoriented edges - dl and db

1. 7:03.52 U2 L R' D2 L2 R2 B2 D' U B2 F' R2 U2 R' D2 B2 F R' D U B2 F L' R D'

Its actually a pretty nice bld scramble.


2. 6.03 DNF. It had parity. I memoed the edges, but at the end realised i still had another cycle that i hadn't memoed. Some of the edged were wrong.



3. 9.01 DNF 2 misoriented corners and 2 misoriented edges.

4. 5.42 DNF, stuffed up a setup move during M2, total failure: had parity.


5 5.23 DNF, stuffed up a couple of pieces. - parity.

6 5.22 DNF - 6 misoriented edges and 2 misoriented corners. parity.

7. 8:35 DNF, needed to do one more edge cycle

 

[ConnorCuber]

sub 3 failure 2:56.14 off by two misplaced corners and two misplaced and misoriented edges.

 

[Faz]

5:41 DNF with 2 edges misoriented!

Never done a 3x3 BLD before.


EDIT:

4:49 DNF with 2 edges misoriented!!!!!

WTF!!!!!
