MBLD : 4/4 17:24.41[11:53.61]
Relatively easy scrambles, my 2nd MBLD attempt of the day, which slows me down a little in memo-phase, and the 1st attempt was a 5 cubes attempt which I got a 4/5.

2 ~4 BLD relay :15:10.91[9:02.04]
2) U R U2 R F2 R' F R' U2
3) D2 B2 L2 F U2 F' U2 F2 D2 B' L R' B' U' R U' B' F U F2
4) f2 R U' B' R2 f2 U' r L2 u2 F' D B2 F2 f u R B f2 L U B2 r' B F2 R F R' f2 U' B' F2 r L u' f B' r U2 f'

Tried implemented some comms into 4x4 centers, works well, wouldn't say I'm good at it yet, but looking forward to get faster time with 4BLD.

Btw, my 2~4BLD relay is always faster than my 5BLD, is that normal?

I think it's normal because pieces in 2-4 relay: 8+(12+8)+(24+24+8) = 84
And pieces in 5x5: 8x6(centers)+24(wings)+12+8 = 92

So 5x5 should take longer because you have more pieces to memo and solve :) (and in 4x4 you can even reduce the number of pieces by orienting wisely)...

I'm not an expert tough :p

2-4 relay has 80 pieces to solve compared to 92, so on the face of it, probably :)

Practice with center comms = sub-10 easy!

A super nice scramble, somebody sub-4 that please.

Also nearly finished my 3style list for wings for a DFr buffer, woop woop. Will publish it soon.

Possible for a comms list for centers involving opposite faces and for U face > Adjacent/Opposite face > U face cycle? I always stuck on these 2 types, I can do adjacent comms freely, hopefully by mastering comms I would get around sub 6 and be able to pick up 3cycle wings easily.

Tbh comms are a trial and error process, if you struggle to do positions on the bottom, set them up visually an figure out how you would execute blind in coordination to memo pairs, i would try and help by giving my examples but most people would be nono's to me and say im wrong although me and nevins have the say bigBLD memo

I can do them sighted with some pauses and think. But not when the blindfold is on, however, comms with the adjacent sides are consistent. Just these 2 types of comms I'm struggling to figure out. Might have to start writing down algs how I do them sighted. However, the one the from U face to other face then back to U face for new cycle, I still have trouble with it even sighted. I feel so stupid now.:fp

That is part of the plan, not to write out an alg for every possible letter pair but for I think the 256 unique cases for adjacent face and opposite face comms. I don't think you even need a comms list for it to be honest, it boils down to the same few algorithms:

U r U' [l2] U r' U' [l2] - an M2 variant
r U2 r' [d2] r U2 r' [d2] - typical opposite face case
r U r' [d'] r U' r' [d] - typical adjacent face case.
f [u'] f' U' f f' U - solving last 2 centers on adjacent faces by cycling Ubl -> Ufl -> Ful
x' r U r' [d2] r U' r' [d2] x - " " " " on opposite faces by cycling Ufr -> Ubr -> Dfl

I set up to one of these cases when I can't see a 8-move comm straight away

Yea I know it is meant to be intuitive, just kinda wanna explore the concept by executing algs.

Edit: I've tried this algs, now I know what I'm missing. I've limited myself too much that I'd never explore the l2 slices. The M2 variant really helps a lot opening my understanding to the comms, so is the 2nd last one, now that I can see how pieces go in place. Thanks a lot Ollie, this does helps. Hopefully I'll be able to sub 6 consistently before 2013 make its call.

Finished a list of speed-optimized 3-cycle algs for wings for a DFr buffer. Will proof read through whenever I next have time and publish within a few days.

Shouldn't be a problem :)
