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 :)

My very first 4BLD success using center comms, even tho scramble is easy. Would've been faster if I used U2, but once I get used to comms I think I'll get quicker.

I found a 17 centre solved scramble :p Apologies for the f b turns - blame my old version of prisma which I will update before I try again. This was the best of 20000 scrambles

How did you count the solved centres on 20000 scrambles?

Am fast scrambler.

Actually I made an excel spreadsheet.
In simple terms: Scramble is pasted in, scramble is decomposed into individual moves, each piece is tracked during each move by using a large matrix, end product is found, 24 orientations are checked, maximum is found. Then I wrote a little macro to make it go down a large list of scrambles.
In complicated terms: Even I don't know any more. It was complicated. Very complicated.

I might upload it sometime.

haha ok, I might make a program for something like this. I've already made a cube structure in c++ so something like this probably wouldn't be that hard to do.

Thanks! I'd like to have some competition, though. It's getting pretty boring...
Mike? =)
I've tried a couple of times, and failed pretty badly. I keep wanting to go fast. I also find it harder to be accurate at competitions I either organize or am heavily involved in running.

But honestly, even without those factors, I'm just not sure I'd have a chance at your streak - it really is incredible.

4BLD: Third succesful solve ever. Very safety memo and execution. Sub-10 should be easy with couple of more solves...

Goal: sub-10 by finnish open (8.12.)
