Talk:Chess rating system

USCF rating
Seems many gaps; I'm guessing this is an error, although I not familiar with the US system. Can someone be rated 1750 or 1950 etc? SunCreator (talk) 02:04, 12 March 2009 (UTC)

Rabar's system
Braslav Rabar also invented a system around the same time as Elo did, but FIDE choose Elo's. Even if it wasn't used it should be mentioned in some capacity. 213.149.51.126 (talk) 16:05, 13 February 2019 (UTC)

Rating inflation / rating deflation
Right now this article says nothing about whether ratings have inflated or deflated over time. In other words, is a 1500 or 2000 rating in 2021 the same strength as it was in 1971 or 1921?

I am thinking about adding something about this, but would like to discuss what the article should say.

The question of whether ratings have inflated or deflated for the average player may have a different answer from the question of whether ratings have inflated or deflated for top player.
