Blindsolving Failure Thread

Chris, I mean during memo I'd realize the stickers that need memo, for example, QU. But upon me trying to make images and start memo'ing it, my brain wouldn't work. The brain fart did not happen upon recall during solving. It happened during memo! It was a horrible feeling to have :(.

I did those solves with M2/Old Pochmann. Using TuRBo/BH is still much too slow (well, it's just not NEARLY as fast since I have to think about the cycles). How would you do the pickup cycling?

Also, I've been doing so much BLD lately with just sentences, like, I'll just say "queen being ****ed by Rowe Hessler" or something like that, and I do that for hte edges, then auditory corners. I've been doing stuff like that so much that making images is much harder now. It wasn't until the 3rd cube that I could actually get the images in my head. If I visited my rooms in my memo then it'd be blank, but I'd remember the sentences I made, and when I'd recall the sentences THEN the images would appear. I think if I do 3bld now I'll go slow and make the images to get back into that practice.

If I wake up early enough tomorrow before work I'll attempt 3 again.

EDIT: DNF(9:28), off by 3 +centers and 2 xcenters. This scramble wasn't that great, other than the midges being easy.
DNF(9:01.24), 3 MIDGES!!!!!!!!!!!!! :fp

Unlucky, hope you get one soon. So is 11:xy your pb? I'm not good at keeping track of my own pbs, let alone other people's.
Atleast you have a 5bld success in comp now, so you can use 3 solves to go fast :p
Good luck, hope you get a sub 10 success soon :tu

Ah yes I know what you mean now. Yes I do this sometimes too on occasion. This happens a lot more often when you're first getting used to your image list. It will happen to the images that don't come up in your first 10-20 solves by sheer random chance too. Make sure you review chunks of your image list from time to time. Like, every morning when you take a shower/brush your teeth/shave/etc. review the A_'s or the _R's etc at the same time. This will help avoid those amnesia moments, but yes I get those too sometimes.

I did those solves with M2/Old Pochmann. Using TuRBo/BH is still much too slow (well, it's just not NEARLY as fast since I have to think about the cycles). How would you do the pickup cycling?

Pickup cycling is an amazing trick, and in my opinion is a completely required thing you must know to do big cubes BLD.

Imagine we have a cube scrambled with (A BC DE FG) as the cycles. These could be for any pieces, but we'll see later that pickup cycling sort of breaks down for orbits where you break cycles.

Now let's say that you forget the BC image. I mean completely blank out memory recall error forget it. In this case your memorization becomes:

(A ?? DE FG)

Now when you read this on the screen you can sort of tell that you're missing letters from the early part of the alphabet. This is not the case when blindfolded solving. If you have a recall delay it's very difficult to remember whether you have letters at the beginning/middle/or end of the alphabet at all. The image is effectively gone from your memory for the time being.

Pickup cycling says let's keep solving anyway, and save that forgotten image for last (often it is the very last thing you will do at the end of the entire solve).

(A ?? DE FG) is our memo. Skip the ?? forgotten image and start with the cycle (A DE) then (A FG).

If you do (A DE FG) you will be able to finish cycling every other image in your piece orbit. To make this work you now have to "pick up" the last forgotten image with the following cycle:

(D ??) or once we remember that the forgotten image is BC we would do (D BC)

The reason D becomes the buffer for the pickup cycle is that it was the first piece you skipped to when you moved past the forgotten stuff.

Doing (D BC) will "pick up" the BC image and still solve the cube.

-----------------

Sometimes you also forget an entire image location, three images for me.

(A BC DE FG HI JK LM)

Let's say that we forget the entire first memory location. Our memorization becomes:
(A ?? ?? ?? HI JK LM)

We will skip the forgotten stuff and do the cycles we do remember, so (A HI JK LM). Since H is the first piece we skipped to, then H becomes the buffer for the pickup cycles. Once we do finally remember the forgotten image location we would use H as the "pickup" buffer:

(H BC DE FG)

Doing these cycles will solve the cube.

-----------------

Pickup cycling really doesn't work the same way for orbits where you break cycles.

(A BC)(D EF)(G HI) are cycles physically on the cube. If you break cycles then you would memorize:

(A BC DE FD GH IG)

Now let's say that you forgot the first two images. Your memorization now is:
(A ?? ?? FD GH IG)

Perform the cycles you do remember: (A FD GH IG)

Now you would think that F, being the location we skipped to, would be the pickup buffer for the forgotten stuff. So we should do:
(F BC DE)

It turns out that you would actually need to do: (F BC AE) to solve the cube right now. The reason the standard pickup cycle doesn't work is that you shoot the "broken into" spot twice during cycle breaking. If you memo-blank on the first shoot to that spot, but actually still perform the second shot to that spot, then this causes problems. I still don't fully understand the theory of why it breaks down myself (meaning I can't yet predict what the correct pickup cycle should be in cases where I skip past the first cycle break shot like we described). I just don't even use pickup cycling for corner or central edge orbits, unless I have a strong recollection that I did not break cycles on this solve, or broke it only near the end when I forgot stuff near the beginning, etc. Only then would I know it was safe to use.

Also, I've been doing so much BLD lately with just sentences, like, I'll just say "queen being ****ed by Rowe Hessler" or something like that, and I do that for hte edges, then auditory corners. I've been doing stuff like that so much that making images is much harder now. It wasn't until the 3rd cube that I could actually get the images in my head.

I think if I do 3bld now I'll go slow and make the images to get back into that practice.

Yes I know exactly what you mean. I used to mentally narrate my locations as well. I would say that if you can remember the audio sentences at the location, then try to do that and DON'T picture the image. However, if you are using images, then you have to stop narrating them. Again I used to do this as well, and it led to many DNFs for me as well. Ideally your mind should be silent while you picture the images, no mental narration at all. Now this can be hard to do, if the occasional word or phase slips in don't fret. But if you say a full, grammatically correct sentence during the process of memorizing a location, then you're saying way too much in your mental dialogue.

Try to realize this early on, because I struggled with this quite a bit for a while in my big cube BLD solves. This may not affect you very much on 3x3x3BLD, but I can guarantee that it will be a bigger issue on 4x4x4 BLD.

I did it a few times early on, but I don't bother anymore. I figure any solve where I need to do pickup cycling is guaranteed to be slow enough that I don't care much about the result anyway. (shrug)

Generally I'd agree with you, but if I took that attitude we wouldn't have had a full podium at UIUC. I'd never actually figured out the rules for it, I just do it on the fly.

Mike, I have to respectfully disagree. I can still get very good times even on solves where I pickup cycle. At least the way I use it, instead of using "think-ahead" while cycling the current pieces, I use "think-back" to try to remember the forgotten stuff. Basically I recall the current cycle, then the commutator, then while executing I either letter search (the current cycles sort of do that for you) or try to remember visual cues about what the image could be. Sure you lose your "think ahead" speed, but you also sometimes can recall the forgotten stuff during your cycles, and as far as solving time is concerned you would only notice the short pause when I notice that I've forgotten the one image, and before I start solving the image after it so that I can still move on. I would suggest to give pickup cycling another try. It is an absolute life saver for those horrid times when you do run into a memory recall delay.
 
It's just that my only really good times are when my memo is completely solid. If I'm doing a pickup cycle, it means my memory isn't solid.

I suppose it might be worth doing for 4x4x4 BLD. For bigger cubes, you can almost always just go on to a different piece type and come back when you remember the first ones. Since I tend to care more about the bigger ones than about 4x4x4, maybe that's why it doesn't seem as worth it to me.

Rowe had an interesting encounter with a pop at Brown 2011, he was searching on the floor for it, and batted it away a couple of times. I didn't see it, I was solving a couple of tables down, but heard about it afterwards.

Hah, I remember that. I was memoing right next to him, and stopped to watch. Quite humorous.
 
I've been trying the advice from the recent article by Joshua Foer, the memory sports guy who set the US record for card memo time. I've been trying to go a little bit faster than I am comfortable doing on 3x3x3BLD, but not ridiculously so. My accuracy this session has been dismal, I've only gotten 3 successful solves out of 12. I'm trying to take detailed notes on what exactly goes wrong when I fail, as the article suggests. I've even done full post mortems on some solves. I'm finding that my errors come from 2 places usually, 1) permuted but disoriented pieces, and 2) edges in general. Although I do mess up on corners sometimes too, I mess up far more often on edges. I find this strange, as I don't really struggle with central edges on 5x5x5 BLD. I wonder if this means that I should slow down my 3x3x3 edges memo to match my 5x5x5 BLD pacing on the same pieces? Or should I just keep trying to get used to the slightly faster pace and try to adjust?

Do other people have trouble on 3x3x3 edges over corners as well? Does anyone who also does/did have any advice on how to improve 3x3x3 edges accuracy while still trying to go somewhat fast? I will of course continue to practice by doing lots of solves, but I'm wondering if I should focus on any part of my technique in particular while doing so?
 
I got excited and got ahead of myself. D:<
38s~ memo, my fastest ever (no solved pieces), I turn as fast as I can in hope of 1:2x.
I get to the end of corners, but I don't feel like I've done enough. Go through trying to find the last letter pair (and letter), when I realise I'm not looking for the last, I'm looking for the first. I had an adjective before the first object. I undid all corner targets, redid them correctly, did parity, did edges with no mistake, finished the solve, 2:09.
M2 edges, Old Pochmann corners (with 1 comm that I recognised while memoing ^^)
D:< Pb is 1:42.

I am in the same boat Chris. I am not as fast as you, of course, but I find that I have much quicker memo when I make my stories interesting, rather than simpler/shorter. Edge memo feels really dense and lengthy, but corners for me feel very spaced out and simple to remember. I try to cut my stories ( routes / words) shorter by just finding simple cycles to memo with pure visualization. I only do it if it's very obvious. So my edge memo is a bit of story + visual memo. I would also like to hear some other ideas on this. 3x3x3 BLD is sort of my main event now, even if I am slow :3
I also tried exactly what you did Chris - I went really fast on memo for about 30 solves and only had about 5 successful attempts. We suck? :P:P

7x7x7 BLD for the weekly competition: DNF [52:42.28, 27:55] - seventh 7x7x7 BLD DNF in a row. This is getting frustrating.

But what was really interesting was the way I DNFed. I got every single X center, + center, oblique center, wing, and central edge correct. What was wrong? 2 corners and 4 middle centers. I didn't even realize that was possible! I apparently picked an orientation that had center parity and didn't realize it, thinking I knew how to solve the centers (which I didn't). I solved the corners and sort of remembered that there were an even number to solve, so no corner parity. But at the very end, I had an odd number of central edges, so I figured I must have had corner parity and solved for it. Apparently the corners were right before I did that, which is why they were swapped at the end.

I'm wondering now if this might be a good way to deal with center parity. Solve for the case I had on my 7x7x7 when I was done, and then find an algorithm that solves that case. It seems like, although the algorithm might be fairly many moves, it might be a braindead way to handle center parity.
