Player rating for tournaments across all installments of Heroes.

In my opinion, it's a well-balanced rating system.
You can even skip #3 and stick with #1.
I understand that one super-leader will negatively affect the scores of the others, but that would be fair enough. If he has significantly outperformed the competition, then he should receive more points, not just a few...

But the first option doesn't take into account the number of players in the tournament and the number of players who have overtaken you. And that's not right. Being in second place or twentieth (with the same personal result) are completely different things, you'll agree.

In the third option, everything is taken into account...
