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

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. 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.
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.
