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

Regarding draws – the point is that there shouldn't be any, of course, but then the question arises: can there not be an even number of games? Why can't a pair of players agree that one wins now, and the other wins later – how do you deal with that? – I think it's impossible. Regarding calculating points taking into account absences: to Optimal: you came up with a good idea there – the coefficient k should directly depend on the number of missed games, i.e., if there are no more than 1, then k should also not be greater than one, but if more than 1 games are missed, then this coefficient should be stricter, for example, 2 – this is primarily to make players realize the value of their empty words... to IronAxe: You see, in the case where a player simply doesn't show up for the tournament, doesn't play a single match, according to the existing formulas, the rating will remain the same, but in the case of a REGISTRATION, but NO SHOW, the rating will decrease, i.e., they will simply stop saying: "register me, I'll beat you all. We'll play then..." – this is simply disrespect for those who are waiting for their opponent at the appointed time, disrespect for the organizer, etc. But if you make the point calculation stricter and let everyone know, I think people won't throw words to the wind so easily... they'll think about it next time.
