Player rating for tournaments across all installments of Heroes.

Starting from the sixth stage, the bonus will be calculated. I will try to calculate it according to two options - the old one and the new one (where the strength of a beginner is equal to 1/3 and there is an increasing coefficient of 1.4). After that, the differences in all three systems will be more significant. Why wasn't the bonus calculated before? Because comparing the strength of players in versions 3 and 5 is meaningless. Now, the comparison will be based on versions. Until the esteemed Fireball offers his system, I will calculate the VK ratings based on three systems. Later, if necessary, I will add a fourth. I calculate the overall rating ONLY according to my system, so please excuse me - I'm not made of steel.
