Or are you still keeping track of what you are actually doing as you execute the string?

Once you have completed your memo you should not have to think during execution. Execution should be like a dumb computer just mindlessly executing a sequence of instructions.

Which is exactly why the transition to multiple cubes has been a lot easier than I expected. Once you got one in memory it doesn't matter that you put it memory yesterday, just execute.

Just curious, unlikely to need in this lifetime: In Multi, how do you memo whether you need the parity alg, for later recall?

For me, I currently memorize corners first, then edges. Then I solve edges first, then corners. When memorizing the corners, if I have parity, I will memorize an odd number of corners. If I get to the point where I'm solving corners and I have an odd number of corners, I know I need to fix parity. If there's an even number, I know I don't have parity. So there's really nothing extra to memorize.

Flipped edges and twisted corners are the bad part to have to remember for multi, not parity. Those can sometimes be pretty ugly, depending on the scrambles. That is generally what I consider to be the main difference between "good scrambles" and "bad scrambles" for multi - how many flipped edges and twisted corners there are.

Non-BLD update:

I've got elected as a candidate delegate of Texas. Non-stop cubing competition at North Texas area is about to start

Great news!

Like Mike said, you memo an odd letter on its own when there's parity. Different people do that in different ways but they ultimately amount to the same thing. Personally I add the letter Z because that's what I do in audio memo. So R becomes RZ becomes razor. Other people might just have an image for R on its own, or use some special category of image, for example @newtonbase has a superhero for each lone letter.

This is why doing memo in pairs is pretty much optimal, it identifies parity in your memo without any other tricks.

I'm an iconoclast and use double letters like BB instead of a dangling letter if there is parity but that's just a detail. If you use single letters you still need unique images for those 24 cases, you don't want to mistake Iguana for IG if you're using it for single I with parity. So four people, four different ways of doing it but it boils down the same: you'll know because there will be something that uniquely identifies parity in the memo itself.

There are so many double-letter memo posibilities out there, not otherwise useable, that I'm attracted to that approach. Joltin' Joe, Miss Monroe, just to get started. I am saving Z for letting X be X,Y or Z.

Yeah exactly. Ultimately it doesn't matter what scheme you choose for mapping from stickers to images. You simply need to be able to map from pairs of stickers, and single stickers, to images, and vice versa. I often think too much attention is paid to different ways of choosing letterings and translating letters to words or images or sounds. As long as you have something that works for you, it really doesn't matter, and once you recognise that, it makes it easier to handle the exceptions or bad cases arising from whatever scheme you choose.

That's the main reason I stuck with it, it was really easy to come up with stuff for most of them. For UU I use an image of two horseshoes because it was hard to come up with words but this is a "whatever works" game.

 

[pglewis]

In the end, it'll be the unique images you use that will signal parity, once your image list is second nature.

I have countries or cities for single stickers, and usually apply the memo to that location or if I'm already using locations (big blind or multi) I just apply it as origin of the object.

I haven't been doing this for a long time, so I might change again some time in the future.

I'm currently trying to not practice non blind solving at all which is quite easy because I have no time at all due to several unfortunate reasons just to try not to repeat ever my 8 DNF at euros anytime soon.

I have a lot of ideas and projects focused on blindsolving, I really hope to be able to share it here in a couple of months or so. Meanwhile keep up practicing and doing nice things everybody

Please do share with us. This is a great place to discuss stuff.

Why would you memo parity? You do an alg, raise your foot (Parity). You do another alg, lower your foot (no parity). If your foot is flat at the end you don't have parity

Gonna need a lot of feet for multi

I had actually thought of that, may try it, but I think sticking to letter pairs as I memo may be better for me. Might forget to move that foot.

I used to leave cubes with parity a couple of cm ahead of the other ones, another option is to group them if you are trying 10 or less.

I've heard that before but I'm afraid I don't quite get it. You still need to memo those odd letters, right? So you already know the cube has parity when you get to an odd letter. Why is it helpful to have some extra reminder that the cube has parity?

I remember us discussing this many years ago, and the main justification for it back then was as a way to verify that your memo is right - if you get a mismatch from how you've set the cube, you know you're probably recalling the wrong cube. Not really much of a benefit; if your memo is insecure enough that you need this help, it's probably not going to be a very good solve anyway. But it is something that takes practically no extra time to do, so from that perspective, maybe it still makes sense to do.

I note if there is parity (3BLD not MBLD) after corner memo... probably like most (I memo corners first). Then I don’t think about it again. During execution I still execute in pairs, sometimes those pairs flow together pretty well for a decent execution time, but either way, I KNOW after the last edge piece that it didn’t have a mate... so do parity and roll into corner execution.

With M2, I’ve noticed that it doesn’t matter if you do parity between edges and centers or at the end.... or at least, I think I’ve noticed that. I still do it in the middle, but a few times I forgot for some reason and did it at the end and it all worked out.
