I am not sure it is worth the effort - the request is possibly aiming at higher accuracy, but intrinsically the rules of the game are not so strict anyway. If somebody is trying to get 10 % higher find count a little cheating helps and you will never find out. So if the request can be implemented easily - fine. But IMHO PGC should not put too much time into the rankings as geocaching is not a competition. I like the statistics, but rather for myself then for comparing.
