Player rating for offline Heroes 3 tournaments!

Greetings to all forum members!
I finally found the time to read the discussion on this topic and decided to express my opinion on the matter.
I don't really understand why there are two difficulty levels; I think those who completed this map on Normal could have also completed it on Impossible, especially since everyone says as one that Normal was harder. I don't know, I haven't played it, but it doesn't seem that way to me. Normal is normal, and why should a high rating be awarded there? If a player goes to play on Normal, it means they have knowingly agreed to fight for positions in the lower part of the table.
Regardless, despite all the arguments, no one has been able to propose a better counting system than IronAxe, so let's just leave it as is, especially since there aren't many opponents either.
Regarding grails, I think that calculating based on the number of tournament participants is also objective: fewer participants means a smaller prize pool.
In general, I support this counting system.
