Replaces your chess.com rating with a Chess Tier Ever wish chess.com had a tiered ranking system instead of displaying your rating number? This extension replaces your rating with a tier, so you can focus on your long-term skill level trends instead of watching your rating fluctuate after every game. There are currently 7 tiers, each with 4 to 5 sub-tiers. You can also turn on the "use USCF ratings?" setting to get a tier that is based on the Elo rating distribution of US Chess Federation players instead of the rating distribution of chess.com players.
