Preparing for the "Van Kanegem" tournament.

Tried to figure out the scoring systems. The result:
1) spent a lot of time reading posts

It's good that you at least approached solving the problem this way – that’s commendable.

2) tried to create my own version

So, you created your own version – calculate and maintain the ranking yourself.
Therefore, everything is in your hands.

3) ran into a problem because I am not familiar with all the nuances of evaluation, i.e., for example, besides the speed of completion, is anything else important?
Because sometimes it seems like yes (parameters and Mercury), and sometimes no (only for those who “joined” on the same day).

For now, this resource works as follows: For each Tournament, they award Grails (a kind of virtual currency on this resource, but so far there doesn't seem to be anywhere to spend them - ideas are under development), and these Grails are awarded for placement in the Tournament, for oil, for pumping up stats, for descriptions, or even for some creative work on the portal. But in addition to this, we have tried to come up with a simple game rating based on playing Heroes. There are three types of systems here. One of them is purely mine, and the other two types are modified versions of it. I don’t quite agree with the modifications, so I announced that I will keep my own rating from Axe, regardless of what the others do. See the link:/topic/2039/
There is a file with documentation according to which I calculate. In my system, only the speed of completing the main task of the Tournament is taken into account. Even the place is not taken into account.
P.S. Richard, I even tricked you a little. The universal rating was aimed at 33%. My rating is loyal to newcomers and severely affects the accumulated rating of veterans. Newcomers – everywhere we open doors; veterans – everywhere we show respect
