Player rating for tournaments across all installments of Heroes.

I thought about the rating again. The minimum completion time (in theory) is still a necessary element for assessing the strength of a Tournament.

Absolutely correct. However, this (theoretical) minimum cannot be determined unambiguously... And if you say that "these guys believe that the map can be completed in N days," for me, it will be the same as "these guys believe that your rating is X"... This is a theory that cannot be proven. And conversely, if you say that you do not know anyone who has completed the map faster than N days, this does not mean that such people do not exist...

Therefore, the map completion limit itself cannot be taken as a criterion because it is unknown. And it cannot be proven. And someone's opinion should not be the basis for making a decision. So, let's start with an evidence-based approach. But this is not solvable... Why build castles in the air? It is not worth focusing on the map's completion limit.

Sorry for the academic style of presentation... ;)

(∑(Ri)(summation over those with a rating) + 20 (or 30) * n (number of newcomers))/1000
And we move on to further discussion.

Of course, I calculated using the original formula:
(10*(60+20)+5*20)/1000=0.9

Your two posts are not related to each other. The inconsistency is highlighted in red... Unfortunately, I cannot yet understand your calculation mechanism.
