Player rating for offline Heroes 3 tournaments!

The idea is quite good. But, as I understand it, this applies exclusively to ranking issues. And what about grails? And how will the ranking be calculated in other versions of the game?

I don't know anything about grails. They are counted separately from the ranking and should not depend on it. I have no idea how the ranking will be calculated in other versions. And in general, for each version of the game, there should be a separate ranking for the player - therefore, as an experiment, in order to somehow determine it, we chose only Heroes 3 for now. And I will only calculate it in the VDV-forever tournaments. In principle, you can ignore it and focus on grails.
Although one does not preclude the other.
