For instance, I expect a GM to play more accurate on average than an average club player. There is certainly a strong correlation with strength and accuracy, but it would be interesting to know how reliably strong the correlation is.

Wild positions will deviate more, short dull games, rich of exchanges and a quick draw will not have many blunders in them, mainly because alternative moves are often almost equally good. But in wild positions the difference in the evaluation of possible candidate moves can deviate quite a lot.

Indeed it would be interesting to see how much ACPL correlates to player strength. I remember there used to be an online database of games and players located at chess-db.com that had a similar feature on the players profile.
But I suspect that the correlation would not be very strong. I bet there are a lot of FIDE masters that are much more "accurate" players than, say, GM Jobava.
