After the brainstorming session, no new ideas emerged.
We'll have to launch a poll regarding the starting point for calculating the rating, as well as which formula to use for rating calculation.
In any case, the official rating will be the one that is at least agreed upon with the community, and not by a single member of this forum.
This is simply the height of bureaucracy and backwardness!
For my tournaments, I will calculate a separate "independent" rating based on the results of only my tournaments, and you can do as you wish.
