Blindsolving Failure Thread

I may as well post my failure too: 12/15 in 53:04.66, memo was 36 minutes. However, I am happy with an average of 1:08/cube.
I usually film my big multi attempts so I can determine where I go wrong:

Cube 7: Labelled a sticker as G, where it should've been N. I also labelled a corner wrong, but picked up on it.
Cube 8: Made a stupid mistake while cancelling a U-perm, finished it off with R2 instead of R.
Cube 13: Missed UR being flipped, I may have seen it but forgot to memorise it.

This entire attempt was not for practice nor to see whether I can handle 15. I simply wanted to examine how often I make the error done on the 7th cube :fp. Because I know rechecking your letters makes it much safer, but it can potentially make it slower too.

6x6x6 BLD (for this week's competition): DNF [31:14.17, 14:05]
Off by 8 obliques (all in the same orbit) and 7 inner X centers. It took me a few minutes to figure out what happened. When I was doing the second set of obliques, I couldn't remember the memo for the last location (which had 8 pieces to solve). So I did one set of wings and came back to them. At that point, I remembered it all, so I went ahead and did them. The problem? I applied that location to the inner X centers instead of the obliques. :fp

That memo time is pretty good for me. If I hadn't had the big memory recall failure on that one location, I might have been close to my PB (and I probably wouldn't have done them wrong, either). So sad.
 
14/15 56:14 [36:58]. Again, 1 cube out. Executed in this order: 15 13 14 9 10 11 12 1 2 3... It was cube number 9 that was out by a setup move (4 corners and edges). Memo was 2-3 minutes slower than the other day (I put it down to having more flipped pieces), and execution was a tiny bit faster, so no PB sadly :(

7bld: DNF 56:35, memo was 28:32, execution was 28:03.

I ended the solve with orange/white on U/F instead of my normal white/red. I don't know what happened. Probably did an M somewhere, since doing M' fixes a lot of centers. Not even the corners are solved, because I messed up the third corner commutator by doing RUR' D' RU'R' D R2 and I 'fixed' it with R2 R' ( I'm guess I thought I did D' RUR' D RU'R2).

I'm not going to try this again for a while >_>
 
4BLD DNF 11:32.91(5:46.44)

Off by 6 centres and 3 corners :fp
I should probably try more centres-only BLD to increase my accuracy. The only problem I can think of is me visualising pieces wrongly when performing commutators, and this scramble had pretty easy centres too :(
 
4BLD DNF 8:41.97 (4:20) in weekly competition.

4-cycle of wings, meaning I definitely memo-ed wrong. But this memo felt way better than any memo I can remember recently, I didn't have any trouble remembering anything.
 
tried making a video for my first BLD attempt, and after i "finished" the corners I showed it to the camera and said something like
so the corners should be done. so you already know if i messed up.
and then i went and solved the edges

yeah, the corners werent even close...
 
Well this is embarrassing.
I'm only posting this because I spent over 2 hours carrying out post-mortems. Now, straight to the point: 7/16 in 58:26[37:xx]. :fp
Regardless of how many mistakes I made, I still continued the execution. I wanted an accurate time without skipping anything.
I found the mistakes quite interesting, it may take time but it's nice to figure out where you go wrong:
Cube 3: Everything lettered correctly, I just shot a corner to the wrong sticker (J instead of L).
Cube 4: Everything lettered correctly, I just shot a corner to the wrong sticker (J instead of L)... again.
Cube 5: During the execution of a U-perm I realised I was doing it with the wrong pieces, this distracted me - thus resulting in a messed up U-perm.
Cube 8: Started executing the corner memo on the edges, slowly undid the errors. While I was finishing the last of the corners it popped, making me lose my place in the algorithm.
Cube 9: While picking up the cube, it slipped out of my hand resulting in an F pre-move.
Cube 10: Memorised a flipped corner, forgot to executed it.
Cube 13: Everything lettered correctly, but flipped the wrong edges and corners. The edges were due to lack of concentration, however I recalled the wrong image for the twisted corner (Cross-over from last night's 12/15).
Cube 15: Recalled the image underwater (UW) as water (WT). I also skipped an image, I didn't forget it I just skipped it somehow.
Cube 16: Not exactly sure, near the end I made a bunch of moves that I couldn't distinguish even by watching frame by frame.
This was slow and very inaccurate, however I'm satisfied with one thing - I didn't label any stickers with the wrong letter :). All of these mistake were clumsiness or purely from a lack of concentration, there were no errors in my memo. :D

5x5 BLD 29:52.91 DNF

off by 3 midges. This is so frustrating because the mistake was a very stupid one and usually I find midges the easiest of all pieces.

My memo for them was DS RF DT IZ GT NUN.
The letter 'U' is for the DBm midge. Obviouslythe m-slice was not aligned when I had to shoot to there. I still shot to DB :fp while I was supposed to shoot to UF.

I want sub-30!

EDIT: Tried another one and got 34:00.66 success. Memo was a bit more than 23 minutes (slow) but I made some mistakes here and there. At least I got it in the end.
I need to practice for Aachen Open.

8/10 in 34:16.90[20:xx]
I think the failure here is forgetting to switch on the camera, now I can't post-mortem them. :fp
I wanted to experiment with memorising in groups of 3 instead of the usual 2, I think it slowed me down. Less times revised, but slower to recall during revision and execution. This execution was 3-4 minutes slower than my last attempt.
-3 corners.
-3 edges.
 
5BLD DNF in weekly competition.

I did corners, midges, xcenters, and +centers in 20:xx. My last +center image was a cake (CK). As I was thinking how to do it, something in my head remembered how the last 3 xcenters were supposed to be CK, because I very clearly remembered what that cycle looked like on the cube, and I remembered thinking to myself that I had to be careful not to do that one in reverse. But the last xcenter image in my route was oklahoma (OK), meaning.....that I switched the xcenter and +center memos. I feel stupid. I'm confused because I always memorize xcenters first, and in my head the route I executed for xcenters should have gone first in my "route of routes". But the more I think about it, the more it makes sense why I memorized the routes in that order.
 
I did 9/10 in 30:36.66 mins.
I did just a SMALL memo mistake. But its ok. I just would have posted it if it was sub-30.
If it would have been 29:xx.xx i would be really angry now:D
Got it on video...
