Can I suggest a “fast player index”: which would work as follows: (Please read “he or she” for all of the occurrences of “he”)

Every time a player makes a move where his total number of games waiting to move is less than 10% of his total games gets a “fast player” point.

For example, somebody with 1000 concurrent games would get a “fast player point” every time he moved when he had less than 100 games waiting for his move – potentially 100 points if he reduced his backlog of games to zero in the course of a day.

A player who has 50 concurrent games, who plays a move in each of them every day would receive 10 “fast player points” – plus additional points if he makes additional moves in some of the games during the 24-hour monitoring period.

I would suggest that “fast player points” be accumulated for (say) a month – so that only those points earned in the previous month are actually credited to the player’s “fast player” index. This would ensure that somebody who, for whatever reason, cannot maintain “fast player” status.

The “fast player index” could then be used as a criterion for tournament entry, game invitations, and so on. It should be available to review in a player’s profile,

This would not disadvantage players who like to play slower and more relaxed games, but would be of great benefit to players who like to finish games (and tournaments) within a few days or weeks of their starting,
