HOORAY:smile03: you finally admitted it yourself! I dare to suggest that you abandon this idea! Or create two ratings... but no aging!
But my colleague is a staunch supporter of the current rating calculation method. I admit that the idea itself is not bad and can also be considered - for those who like it. Therefore, at one time, I also took on helping him develop and balance this method. That is, my opinion is neutral. I am simply, in a sense, a co-author of this calculation. No more, no less. Whether to apply it in practice or not is up to specially trained people to decide. :) So you don't need to persuade me...
You might not believe it, but I did... it was after that that I realized that this task has no solution!
By the way, maybe instead of introducing an increasing coefficient, it would be better to dynamically change the "Scale" (i.e., the maximum number of points for a tournament).
