For example, I don't really like the idea of aging.
In my opinion, it would be much better to organize a cyclical rating. That is, once a year (for example, on January 1), there will be a complete reset of the rating. And at the end of the year, you can determine the best player based on the results of the year.
In my opinion, this would be the most correct approach, because at the beginning of the year, everyone will start from the same positions.

Or, make the aging rate 100/12 and age periodically once a month, for example, on the 1st. This way, we will have something similar to the current rating.

IMHO.
Sincerely.
