pls
What was the old rating system like?

Well........... you had to oil the wagon wheels a lot. Sometimes the horses pooped on yer feet if the wagons design had it sittin' too low. But I digress. The newer version is just different, not sayin' it's better.

I think it was a reputation rating as in who a strong tournament and how many tournaments and matches has a person won and winning streaks maybe also brilliancy and immortal games and world title and grandmaster titles / hope this helped : D

"When I have white, I win because I have white. When I have black, I win because I am Bogolyubov" - Bogolyubov
"I can give God pawn and move" - Steinitz
"I can give Steinitz pawn and move" - Ubik42

I'm thinking the OP was referring to the chess.com rating system before they changed. That was before I joined I guess. I'm sure the old systems formula can be looked up, right?
Please, explain detailed what was the old rating system on chess.com like?
