Player rating for tournaments across all installments of Heroes.

I have the impression that Dmitry AS hasn't seen or understood the formulas used for the calculations. Otherwise, he wouldn't be writing what he's writing.

I doubt he hasn't seen it... He's just presenting his point of view, believing it to be the most rational solution for calculating the rating. After all, you, Iron, only suggested whether it's worth fighting over this? Otherwise, we'll be at it for another year... :D
