Player rating for tournaments across all installments of Heroes.

Is this rating the current player rating from previous tournaments, or just the rating earned by players in this tournament without considering a coefficient?

The calculation uses only the current rating (which takes into account all the player's tournaments), which, in theory, should reflect the REAL strength of the participating players. That's why I'm fighting to eliminate all random factors... The rating earned by players in this tournament still has some random character, because one result is not an indicator of strength...
