Player rating for tournaments across all installments of Heroes.

-taking into account the position, result, number of participants, and their strength in the system is not a problem.

Here is my rating system:
1) The result is taken into account (non-linear part).
2) The position is taken into account (linear part).
3) The number of participants and their strength are taken into account (bonus part. It depends on the number of participants and the average rating in the tournament).
All of this already exists, but few people are satisfied with it.
