while something is better than nothing... and the 'simple' formula would be to just take the total days/hours to complete a game and divide by the number of moves-
the math should take into account the time remaining for each player-
so in one case where my opponent took 19 days to make 3 moves... i am sure it took me < 4 days to accomplish the same...
however- rather than nothing- please do simple first! ;]
