Player rating for tournaments across all installments of Heroes.

As I understand it, this coefficient depends on the ratings of the tournament participants. I would just like some clarification on this: is this rating the current rating of players from previous tournaments, or only the rating earned by players in this tournament, without taking the coefficient into account?

But it will do so fairly and eliminate the effect of randomness in the matchups, which is very important.

That's why I decided to support the proposal to use it.
