You save all information about every move. so it'd be great if you could calculate a kind of average moving speed. even better then that would be a kind of movingspeed density-function: for example: 30% under 5 minutes, 40% under 2 h, 20% under a day and 9% under a week.
Or you could add to every player a statistic WHEN he makes his moves (at what time).
I can imagine that this is a lot of work and perhaps not everybody here wants it (and perhaps it is also a lot of work for the server (weekly oupdates of the figures should be enough))
a little step in this direction would be an extra column in the MAP (general&month) about the average moves per day.
