Here's an idea. Why don't you just play twenty five straight 3/0 games and then play twenty five straight 5/0 games and then play twenty five straight 10/0 games? After each set of different time controls you will have your separate ratings. Got it? It's quite simple when you take a minute out of your day to figure these things out.
Expand the rating categories
Sort:
Chess.com should have more rating categories. For example, 3 minute and 5 minute ratings should be in their own categories. I want to try 5 minute games but my blitz rating is for 3 minutes. My 5 minute blitz rating may not be the same as my 3 minute blitz rating.
