Player rating for offline Heroes 3 tournaments!

The game's difficulty might be the same, but human players are still in UNEQUAL conditions, regardless of the map's size and complexity, assuming the players are roughly equal in skill.
And how will you explain to players on Impossible difficulty why they have a lower rating than players on Normal, assuming everyone considers themselves to be skilled players?

Let's be clear from the start – no one should have to prove anything to anyone or provide explanations.

If a player disagrees, they should take the keyboard and type until their disagreement reaches the others... I see that only about 10 people are involved in the rating issue. And they are all undoubtedly playing on Impossible. Why, as you rightly said, create extra problems by combining incomparable parameters into one formula? Keep a separate rating for Normal, and a separate one for Impossible, and that's it?

Do you think those who play on Normal care about the rating? I won't say for sure, of course, but nevertheless, I think they probably don't care much about their rating... I don't want to offend anyone, but my understanding is this: if you want to participate in the rating, play on Impossible and compete. This will be the most worthy and respected choice.

Honestly, take any analogy from sports. It's not for nothing that there is a division into leagues, categories, etc. For now, these are all experiments. But it seems to me that this unclear "bias" has been going on for too long... You can't embrace the unmanageable. Let's see what percentage of tournament participants will submit a save from Normal, and we'll draw conclusions based on that...

And right now, the main thing is to refine the mechanism. And there is no need to punish the majority for the sake of the minority. This will be a Pyrrhic victory. In my opinion, it is better to spend efforts on teaching all those who want to play the game, so that they can easily start on Impossible, than to try to adapt the tournament work to several categories of players. And there will be one save for everyone, and no disputes or explanations... And it is better to do this as soon as possible, while there are still those who want to create something...
