I don't think that was legit auto-timing :-)

I'd like to laugh at just how really nerdy they DO look, but I'm afraid my grandchildren will be working for one their billion-dollar conglomerates some day.

Question: are all cubes identically scrambled before time starts?

Hold your horses, What was the wind reading and altitude?

Good point, what is the average (and standard deviation) of the number of moves needed to solve the cube ? Roughly how many distinct scrambles are there that require that average number of moves to solve. There had to of been a paper on this back in the early 1980s.

for me, the amount of time required/number of moves are the same: ∞

He spent some time looking at all sides of the cube before making the moves. They should add that initial analysis period to his time.

I nearly laughed a kidney out my nose on that one. ...

There is a distance measured in moves that separates every possible state of the cube with the solved state, call that the origin. What is the average distance of all the possible states from the origin.

Yes, you and I may take a random walk through the space and never reach the solution but my intuition tells me that we never move much further away than when we started....

ok, I found it;

something like 20 moves,
