Player rating for tournaments across all installments of Heroes.

We need to devise a rating system for blitz games. The existing systems don't seem very suitable for it. After all, the results will be in different units of measurement – days, gold, mana, HP, etc. Plus, this rating should somehow be linked to the main rating.

I won't include blitz games in my system. They were planned as training tournaments. You don't need to spend a day on such a task, let alone dedicate a full day to completing a map. Therefore, I think that awarding the leader 100 points in the rating for such a task is too generous.
