Player rating for tournaments across all installments of Heroes.

5. I believe the map can be completed in 7 days (or at most 8), and the winner took 9. I didn't achieve what I intended only because of the huge lack of time (I only had one evening). Plus, I wasn't lucky with the map generation (if I had been, I would have been able to finish it in one evening).
So, we can conclude that in at least 4 out of 5 tournaments (and maybe all 5, if I was wrong about Heroes 5), the winners did everything perfectly. And I think this is not a coincidence, but a pattern. Therefore, we can forget about adjusting the minimum completion time, as it is too poorly defined.

A formula with 4 variables is a minor thing. I can write it for you tomorrow. It will be quite logical (consistent with ALL previously discussed basic principles), it will stand up to checks on extreme cases, etc., but what's the point? Some coefficients will still have to be taken arbitrarily, this formula will not be the only possible one (immediately questions like, "why exactly like this?"), and most importantly, it will be just one of many systems existing on the portal, and everything will remain as it was.
