Maybe also 5x5x5.
Since most speedcubers begin with centers, we should run various metrics on the current 4x4x4 scrambler and see if the centers are random enough. If not, we can apply a random scramble to the centers (ignoring everything else) followed by some amount of random moves.
It should be checked that this doesn't compromise the randomness of other parts of the puzzle significantly.
(Perhaps only use this for speedsolve, not BLD?)

Consideration: Could a reduction-style 4x4x4 computer solver produce scrambles that are at least as fast and accurate to scramble as current scrambles?
