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

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*)
