Player rating for tournaments across all installments of Heroes.

So at the moment we have three options for calculating the rating:
1 - Non-linear (IronAxe's version), here there are two variants: 10% decay and 33% decay, plus taking into account "allowable limits" when playing for speed.
2 - Oscillator (AmberSoler's version), also several variants: 10% decay, 33% decay, no decay, the linear component is calculated from 0 or from any value.
3 - Oscillator+Bonus (my version) - non-linear component without allowable limits, linear component is calculated from 5 points, a bonus is added to the total result, no decay.
All these systems have a right to exist, and time will tell which of them is better.
For now, I will try to calculate the general rating for everyone who played on the portal across all versions. I will calculate it using my system. I'll see what comes of it.
