Whoa 22 moves!

Wasn't it calculated that it takes an average of 23 moves to optimally solve the cube?

I think it is 21 now, chuber. I can't be sure but I heard that somewhere.

No, the average optimal solution length for Rubik's cube positions is estimated to be about 17.7 face turns.

There isn't any position yet known to require more than 20 face turns, and it's been proven that none require more than 22 face turns.

And congratulations, Jimmy!

4 moves more than optimal... U D L' F2 R' F2 R U F U' D F2 U2 L' U2 B' L' B (18f*)

Wow - that's totally awesome. I agree with ConnorCuber - I think that record will stand for a very long time.

And it was not an obvious easy solution at all (at least not to me) - very pretty. Well done!

As far as we know, it's now possible that someone may attempt an official event without any chance of breaking the WR on that attempt.
(Upper bound on God's number is 22.)

Careful, Lucas. The *proven* upper bound on God's number is 22, but almost every cube theorist agrees that God's number is 20, even though it hasn't been proven yet. So it will still always be technically possible to break the WR.

I'm not convinced that the 2x2 single WR is always possible to break, incidentally.
