My solutions are based on M slices too I'm afraid

UF-BD-UB,

U M' U M' U2 M U M U'

UF-DB-RB

U' R' U M2 U' R U M2

FYI. I've updated the oldies rankings:

The unofficial spreadsheet has gone a little quiet recently. No PBs guys?

I've started doing a bit of 2x2 practice. My latest session was a 4.55 Ao50.

U' R' U M2 U' R U M2

That's a nice alg! But appears to do UF-DB-BR... For that one I use D' R' U R U R U R' U' R' U' D. Yours would probably be better, if I can learn how to use it. Mine is derived from my edge system and I can immediately identify how to do it, even if I don't remember anything about what algs I've used for what case.

Another 5000 timed solves done (in like 3 month and a half). I've improved around 0.3 seconds, which at least is more than last 2 times.

Apologies. Try F R2 F' M2 F R2 F' M2

Edit: You could always use an x rotation to switch to U moves instead of F.

Wow, all the recommendations against y rotations. I probably do at least 1/3 of my BLD algs with y rotations as a setup; I often find myself not having to rotate back for several algs in a row because I do so many of them after a y' rotation. It is true it's almost always specifically a y' rotation; that just sets up to so many nice commutators in so many situations.

I don't do any for 3BLD but once I get further into edge comms it would cut down on S moves which I dislike.
I do use them for 4BLD centres.

I see you all use UF buffer. I am still on DF. i am intrigued to switch to UF, but first I want to go on some comp with what i am used to. I use some y rotations when I do +/x centres. It is hard not to use it, much easier to 3-cycle centres.

I guess it's opposite and most of us use DF. Anyway I use DF and I'm not going to switch.

I had a bunch of algs for corners with y/y' rotation but I found on Ishaan's list that they can be exchange with setups like D/D' or R etc.

I'm DF and have no plans to switch. UF is trendy but I've yet to see any compelling explanation why it's objectively better than DF.

I'm DF too hence my confusion coming up with the comm for @JanW

 

[mitja]

Ok, so mostly DF. I would understand it is easier to track pieces during memo with UF. what about 3-cycles corners? Do you use UBL buffer of URF? Do you switch buffer a lot? I move buffer on centres sometimes, when it is in the way of a setup, but just sometimes.

I use UBL but no buffer switching.

All this talk has made me immediately change my OP corner setups for J, K, V, W, and G. My execution is still ~1:30 or a little more and it's not difficult to make those changes at my safe speed. D/F/I is just a nuisance, being on both the U and L faces, which leaves initial F face turns or rotation as a necessary evil.

On rotations: I do use x' rotations during M2 now for E/F/G/M/O/P to avoid B face turns and find it very natural after practicing that way for a little while.

I don't see why it would be easier to track pieces with UF.

I use UBL for corners.

Yes that is a good point. I was thinking of corners when I commented above. For edges I do X rotations a lot.

Let us know when you pass 65,535 / 0xffff timed solves.

Quick comp question for BLD:

After finishing your solve, do you (or may you) look before stopping the timer or do you have to stop the timer before looking?

I realise that once you look, you can touch the cube again, but I’m wondering about finding the timer to stop it. Or... am I over thinking it?

What are you using for G?

Yes, I believe you can look but don't touch. The timer is easy to find though.

If the competitor is not touching the puzzle, they may remove the blindfold before they stop the timer. They must not touch the puzzle until the end of the attempt. Penalty for touching the puzzle: disqualification of the attempt (DNF).

[Edit: my lone official attempt was with a Stackmat and it was easy to find with the blindfold on, keeping in mind I'm very familiar since I use a Stackmat at home]

What are you using for G?

I was doing F2 R', now D2 R
