Player rating for tournaments across all installments of Heroes.

I suggest considering the linear system starting from five points for the following reason: it is close to the minimum score obtained in the non-linear system among all the tournaments held (5.65 for Evil_Hearte in the tournament for the fifth game). So, this is not an arbitrary number. The non-linear system is suitable for comparing two tournaments only in one case: the map was the same, and the starting save was the same. Otherwise, we are comparing apples and oranges, or even 100 meters and 400 meters with hurdles.
