Player rating for tournaments across all installments of Heroes.

My bonus directly depends on the average strength of the tournament. It's also not an arbitrary number; it's borrowed from tennis, where a strong player receives a lower rating for winning against a weak player than a weak player receives for winning against a strong player. Starting from the second round of the tournament, this bonus comes into effect. Since the player roster is starting to become more or less defined, there shouldn't be any significant fluctuations in the bonus.
Although, for a multi-stage tournament, a slightly different system might be possible. The whole question is what we want to measure. After all, a player who has played more games has a higher chance of achieving a higher ranking. But the thing is, that player isn't the only one. There are several of them. In addition, it was suggested to also calculate and separately recognize the winners for each version.
