It is the absolute difference and not the percentage difference that matters correct?

I'm not sure I understand your question. You're saying one should compare errors rather than error rates? But subtraction commutes with multiplication by the number of moves because both players are playing the same number of moves.

Anyway, this is just a rough calculation to get a feeling for what's going on.
