Rating system for online games in Heroes of Might and Magic IV.

How will this be taken into account in your formula?

Good question... Considering that the strength of a tournament equals the sum of the ratings of all players participating in the tournament, this formula needs to be implemented correctly, but it will result in a large number, which is probably why they use a coefficient of 6000.
My formula needs to incorporate this in a way that avoids dynamic changes.
Hmm... I'll think about it and post another formula tomorrow, and recalculate the ratings again :) At least it gives me something to do when I have nothing else to do.
