Player rating for tournaments across all installments of Heroes.

I need a specific number of days for each player. Set a clear task and get a clear answer...

I already did :)
Why does the losing player with a low rating get a rating increase of as much as 30%?
Why does a player with a lot of rating, taking last place, only decrease their rating by 6%? He didn't miss the tournament.

Regarding the numbers - first, just calculate the results of the tournament.
Then, having your numbers in front of you, I'll tell you mine for further experimental calculations. Okay?
