time/move

The time move stat doesn't really mean much if you select an opponent based on it and he turns out to be playing 300 simultaneous games.  How about making it time/move per game instead?

 Short answer - it is  time/move per game.

Excluding vacation time, if your opponent happens to habitually abuse it.

As Erik put it:-

"you take the total time it was your move in ALL of your games and divide it by the total number of moves you have made."

 Makes absolutely no difference how many games he is playing; it's an average.

If it were actually time per move it would make a difference since a move on average every 5 minutes would result in a move per game time of 25 hours with 300 games, hence the question.

If you look at the prior answers it turns out to already be time/move/all games though.

 Pretty sure it counts vacation time, actually.

Does too! Does not! Sounds like a FAQ entry is needed.

When the status of the game is "Vacation", the game clock is not running down. There is nothing to count.
