The World Cube Association requires "equal probability for each state" by scramble programs used for their events.

You're right that a large number of rotations will result in something indistinguishable from random by an individual, but that is not sufficient according to WCA regulations as it's not uniformly random.

That’s not supporting your point, a solution that’s harder to mess up is suggested. Secondly, they specifically don’t want a truely ranodm sequence as they require a minimum number of moves from a solution.

If I can hand you multiple sets of 10^10 cubes and you can’t tell which method was used that’s what I mean from indistinguishable not simply humans can’t tell.
