On 4/5BLD wings: for the letters K C and W, do I have to shot the opposite letter, when I have an odd number of targets?
(Uh, hard to describe here haha)

Do you use spefz?

 

[TheCoolMinxer]

Do you use spefz?

Yes, I don't know how I should say it haha, correct me if I am wrong but for the targets FL, UL and BL maybe then?

Edit: sorry if my english is awful sometimes

The only targets for r2 wings where you shoot to the opposite letter are FU and BD (I and T for me, for others probably something different). These are the only two targets on the r slice other than your buffer and your target position, which don't get swapped by an r2.

I found decent r2 parity algorithm with ksolve and it's fairly easy to learn

r' U2 r U2 r' U2 x r U2 r U2 r U2 r2 U2 x' r' U2

I've switched to this now

Shouldn't it be:
r U2 r U2 r' U2 x r U2 r U2 r U2 r2 U2 x' r' U2 ?

Edit:
Oops, it's ok. I've checked what it does. I think both versions may be applied for 4bld.

5bld parity: does it occur, when I have parity on midges/corners? And what is the best alg to do then? I would do y2, set up move to Rw2 F2 U2 r2 U2 F2 Rw2 and set up move'. But I saw a parity alg from CHJ which looked quite nice(alg?) What would you do?

I leave DF and UB swapped and then F2 (Rw2 F2 U2 r2 U2 F2 Rw2) y (T-perm) L2

Why do I keep DNF'ing on the 4BLD practice solves? I write down the memo, check, and double check it, and when I excecute, I only get about 40% solved. Why is this? When I do sighted solves, I am perfect 100% of the time. I would like to fix this fast because this is getting very annoying.

I'm guessing center set ups. Solve everything but centers, then just memorize in small groups the centers, execute, and check every 2 centers.

Set ups are very hard to miss on sighted solves, but are definitely part of the problem when blindfolded.

Thanks! I will try that!

I do centers with 3-style. Yesterday doing +centers I forgot about one 3-cycle. Is there a way to fix centeres when you miss one 3-cycle but not by inverting solution to the point you missed. I was watching Noah tutorial about it but on 3x3 and I'm not sure if it works on centers in 4bld or 5bld.

 

[Ollie]

It works for all cycles.

So if you have the cycle (ABCDEF) and you miss out CD, you will be left with the cycle (CDE) at the end. So the rule is, the left over cycle will always consist of the letter pair you missed plus the letter that proceeded it. So execute CDEC to fix it

 

[h2f]

Thanks.

On 4BLD, I memorise corners last and solve them first, and if there's corner parity, I solve it at the end of the solve. What's the best way to remember if there's corner parity? What I've been doing all along is remembering if I have an odd or even corner targets, though I don't find this that great.

I've seen people to cross their legs if they have parity.

 

[moralsh]

Make parity part of the memo as an image or a word and stick it at the end of your memo. Or just do whatever you have to do to avoid it (way easier if you don't execute them first, I guess)

 

[cmhardw]

I use my auditory memory and actually say "parity" out loud, quietly, when I have it. It "echoes" in your head for surprisingly long if you actually hear the word spoken.

 

[tseitsei]

I've seen people to cross their legs if they have parity.

This is what I do. And for 3bld I do this if I have flipped edges

 

[h2f]

I'm looking for an alg for double parity -. I mean I do corners first and if there's parity I switch UBL and UBR. Next I do centers and edges with r2. When there are two paritie I do r2 parity with Robert Yau's alg and next edge parity doing r2 U2 r2 Uw2 r2 u2. But It's a lot of moves and I guess it might be something shorter. Is it?

For 4BLD centers, using the U2 method, if I break into a new cycle with a U layer target (whose alg isn't U2), and the cycle ends, could I just do U2 instead of doing that target's alg? I've been considering this and don't immediately see any problems.

Wouldn't that destroy the wings positions?
