I was actually just starting to figure out the thing about the centers. I didn't see them noted and must have missed where that was mentioned. I spent about an hour just moving sides around and seeing what changes and what doesn't change orientation, and noticed that if all 4 were fixed, sometimes after aligning the centers all 4 would be wrong.
One question though... how much faster is this than doing position first and just fixing the (usually only one) orientation problem with M'UM'UM'U2 MU'MU'MU2? One way or another you need to put the cubes in the right location, so that should take the same number of moves, but isn't it faster just to do the 12 move switch rather than having to keep chasing down sides and doing patterns that aren't always predictable? For me, on a random cube with "final six", the way i do it is usually either 20-24 moves (if one side is oriented wrong), or 10-12 moves if they're already fixed. Essentially i'm wondering how the 12 move zero recognition time thing stacks up against messing with the orientations. --- In [email protected], "Mike Bennett" <[EMAIL PROTECTED]> wrote: > > --- In [email protected], "zethusamphion" > <[EMAIL PROTECTED]> wrote: > > > > Ok, heres the problem i keep having.
