The chess rating system is, in my opinion, the best overall!
When I compared my rating system with the chess rating system, I found that when strong players win against beginners in chess, they sometimes receive 3-4 times more points than in my system. And since, in the past, the practice of accumulating points by playing against weak opponents was very common among some players, I didn't consider the chess rating system. And to prevent this from happening, the system should remain unchanged, in my opinion.
