1) scoring system (we still haven't finalized it)
a) we need to delve deeper into the IronAxe rating calculation

This system accounts for practically everything.

b) otherwise, we analyze my version
2) rating decay
3) tables in the first post (keep them or should something be changed)
Please, let's only discuss these issues, and only these. No off-topic discussions.

In your version, the following points need to be addressed:
1. In a tournament, the leader should have an upper limit on the number of points they can earn, which will be the same for any online tournament. But in your version, there is practically no limit to the rating gain. The more people participate in a tournament, the more points a potential leader can earn. In another tournament, if there are fewer people, the leader receives fewer points for the SAME first place. In my opinion, this flaw will surface sooner or later.
2. A new player should have a real chance to catch up with the leader in the rating, at least within a year of diligent and successful games and victories in tournaments, considering that the rating leader has already been on the forum for three years. If a new player wins tournaments (takes first places), this can only be resolved by either rating decay or annual rating reset (which is not a good idea).

In my opinion, these two points have already been resolved in the VGAP system. We are waiting for mathematicians to either confirm or refute this.

The system is simple: more points - higher rating. Victory is 1 point, draw - 0.5 points (rare), defeat - zero. This simple scheme summarizes tournaments held under any system.
=========================================================

This simple system is not a rating system. This simple system is a definition of points for ONE tournament to determine the winner and distribute places. It can only be called a rating with a big stretch
