AbigailII: well in a definition you would be a fast player as as soon as you logon you play your games quite fast

according to your opponents you arent though .. they only see you move once a day and dont care wether you are logged in the rest of the time or not

thats why, from the opponents point of view, i would like to suggest taking the average waiting time per game in which its your turn, but you didnt move yet (wether you are online or not) .. thats seems to me the best way to determine the fast-ness of a player (according to his opponents)

and split it over various game types please ;)
