Chess.com (Glicko) rating-system in relation to player-level

Sort:

I researched a lot about the on chess.com used Glicko rating-system. There are already some very good Posts about how it works and what the difference between other systems is on this site, so if you are'nt familiar with the different systems you can just search for it! But I realy cant find anything about the relation between the rating-score and the player level. From what score you can say that you are a good player and from what score you are an expert?

I got this from wikipedia. This refers to the Elo-system (the most popular one):

Rating range Category
2700+ No formal title, but sometimes informally called "super grandmasters"
2500–2700 most Grandmasters (GM)
2400–2500 most International Masters (IM) and some Grandmasters (GM)
2300–2400 most FIDE Masters (FM) and some International Masters (IM)
2200–2300 FIDE Candidate Masters (CM), most national masters
2000–2200 candidate masters, experts (USA)
1800–2000 Class A, category 1
1600–1800 Class B, category 2
1400–1600 Class C, category 3
1200–1400 Class D, category 4
below 1200 novices

Now my Question to you is to make a similar table that refers to the Glicko-System! Is there something like an rough rule like Elo - 200 or do you know a similar statistic that refers to Glicko? I really hope for some help! With best regards!

P.S. Sorry for my English!

A lot depends on what the starting ratings are, because that can skew ratings one way or another. I differences are more pool based than anything else, and while there are some correlations between Chess.com > FIDE that the isn't a great formula, though lots of people post suggestions. The formula is also not the same for all rating bands, with different potential ranges at different bands.

You might find the tail wagging the dog. At any point in time, a players skill level is fixed, but the rating they get for it depends on the other players in the pool. So if I am simultaneously 1200, 1400 and 1600, depending on the website and time controls, what is my category? You might need a system for each pool.
