I do not use the Specffz Lettering Scheme for memorizing, since I think I am better at my own Memorization Scheme. Can this be the problem in my memorization?
I dont think it will be a problem. It is not that one form of lettering scheme gives an advantage over the other.
My lettering scheme is not used by anyone in the world. I learnt from a 12 year old Youtube tutorial, the best way I can describe it is a mix between chinese way of lettering, and spiral lettering around the cube.


TLDR, it is totally fine with having your own lettering scheme.

I recently started BLD again. I use the old pochmann method. This was the algorithm that Jperm showed for parity, which is just an R perm:

R U' R' U' R U R D R' U' R D' R' U2 R' U'

I don't know why but I never liked that alg... below is the R perm I use in my normal pll.

(U) R U2 R' U2 R B' R' U' R U R B R2

I I tried including a pic a showing in what position either alg will solve the case normally but it wouldn't upload.
A normal case would be white on top, green in front, and the bar facing me(U layer face)

My question is, and forgive my ignorance, is shouldn't my R perm(the second one) work for parity by doing it this way?

I've attempted a few bld solves using it for parity and was left with a mess. Granted the mess could've been some other mistake, I would just like to make sure that given that the cube is in this position between edge and corner orientation, with green facing me, white on top, that this would work.

Since I would have to perform a U move at the beginning of parity, would it be good as it is or should I do a U' after the alg? It seems like it should just fix the edges and corners as is, but I may be looking at it wrong.

Thanks!

there's a reason people use the RUD R perm for parity, and that is to avoid U moves before the alg as you can mess them up pretty easily. Plus, I don't think you should be using B moves for an R perm or any PLL(except for A perms, the BLDer A perms seem to be good) in general.
The B move in the R perm I use seem more like wide l U' instead of R B'.
I've used it so long that it flows well for me without thinking about it.

But doesn't the second alg essentially do the same thing as the first?

At any rate I figured it out. The R perm I normally use in pll works fine, it was my questioning if I was setting it up correctly with the U move to begin with get the edges and corners to flip the right way.

I tried it a few times with eyes opened just to be sure I wasn't messing up somewhere.

Now I'll try it the next bld solve that involves parity.

I apologize if I wasn't clear on what I was asking to begin with.
Any R perm will work, the initial move was what was confusing me... when in doubt, test it.

Is there a way to generate edge only scrambles that are 7-algers without any edge flips.
Currently practicing edge only scrambles to get used to 1-passing audio memo, it's going ok-ish if it's 6 algs or 5 or even 6 with an edge flip as I just do flips visual. But if my audio memo becomes 7 letter pairs I really struggle. So that's why I ask, to practice those cases. Also if anyone has any other advise on this please feel free to share.

I neglected to thank you for your response, I do appreciate it!

I believe you are correct about the algorithms. I've used the one I was talking about a a few times and although I managed to successfully solve it once, I believe it messed me up a few of the other times.

I either need to work on one alg or the other, or just do the edge correction at the end.

Thanks again!

I know about old pochman method to blind solve 2x2 but I've been looking for a better way. if anyone knows any other blind methods id love to hear them

Ok i feel like a noob.
i learnt how to solve a cube in the last 2 months without learning the names of ALGS. its just all there in muscle memory.
now that im making the move to BLND and im trying the BOP method, i know i need to know how to J Perm and JB.

The method on this site lists how to do a JB but not a J Perm and every google search just sends me to the YouTube channel or website of JPERM

can someone please help and tell me what the ALG is for J perm

thank you , i just confused me as in the BOP method it says JB for all but 1 ALG combo, the odd one says J-Perm so im guessing this will be JA from your explanation.

Thank you so much, i have literally been sitting here going stir crazy lol

No problem :)

The J perm is in a list of algs called PLL, which stands for permutation of last layer.
May I know what website/video you are using to learn blind by the way?
And how have learnt how to solve a cube normally?

A lot of cubing knowledge is all connected together depending on what method you use and how you learnt it.
I have to go for now so see you :)

so i first learned Roux from the JPERM video
(1) Rubik's Cube: Learn the Roux Method in 10 Minutes! - YouTube

i was directed the BOP on this site at this link
BOP method - An OP variant for the Beginner's BLD method using UF/UFR. | SpeedSolving Puzzles Community

i was told as ive never done BLND this new method may be a good way to learn as its slightly more advanced then beginners method but not too advanced to be impossible to learn .

let me know what you think as im more then open to other suggestions on how to learn BLND

One frustrating thing is going through assigning pair names and ending up with an uneven number, which would mean I made a mistake.
Even more so is going back and checking and still coming up with odd numbers. I know there's a mistake somewhere, but can't tell where.

I'm to the point I'm not writing them down, and working on not having to place my fingers as much to keep up with pieces. But this happens even if I write them down and place fingers.

I don't know anything else to do except keep looking.

If anyone else has had this problem but found something that helps, I'd really appreciate some advice.

Thanks!

If the tracing it's ok, the odd number mean a parity.

BOP is a good method. The con of this method is that it is not tested, and its new.

The well tested beginners methods are M2/OP, and OP/OP.
Orozco and Eka also do not have that much testing among the beginners as it is relatively new.

What I was talking about is if sides are even and corners are odd(and vice versa), that means I made a mistake... they have to both be even or odd.

I just don't get why sometimes no matter how many times I recheck it, it comes out un even, because I know that and even number on both means no parity and odd means parity.

Sighted solves can help a lot in identifying your tracing mistakes (other types of mistakes, too). Just solve two pieces and check if the cube looks as you expected. Once you reach the last one or two pieces, it should be much easier to find your mistake. Works for edges and corners.

Thank you! Yes, sometimes when I just can't figure out what I've done wrong I go ahead and solve it sighted and see where I was off, but still hard to tell why I'm missing it.

I think my problem arises when I have more than a few cycle breaks, I'm not accounting for something and like standing too close to something, I can't see it.

It's like a blind spot because I've noticed if I go back and change the first piece I got to choose I wind up with all even or all odd. I know nothing has changed except my perspective.

Hopefully with more time I'll get to where the "blind spots" vanish.

Thanks again!
