I haven't heard from anyone else lately. It's not because the system has become so complex that people can't figure it out or don't want to.
Regarding your suggestions, I'll express my opinion.
1. I support aging by 1/10 per tournament.
And here's why. Let's take 2 players. 1 - won the first 2 tournaments and skipped the 3rd, 2 - played in all 3 tournaments, performing decently - 50 points per tournament. What do we have with aging at 1/3: the first has 111 points, and the second has 108 points.
And if the aging is 1/10: the first will have 171 points, and the second? - 135! This is a slightly fairer ratio.
2. Everything is clear here.
3. The oscillator is a rather ambiguous thing that can both add and subtract points. But I'm still for it.
4. I'm for a 100-point scale.
5. A minimum guaranteed rating is not needed.
6. As I understand it, this coefficient will increase the points for all participants in the tournament, including the winner => his point difference from everyone else will become even greater. What is the point of introducing it? How can this coefficient then, to quote: "somehow compensate for the imbalance caused by the appearance of a strong player in the tournament, who will significantly 'lower' the bar with his exceptionally strong performance...." If I misunderstood something about the coefficient, please explain.
