This is FIDE OTB at long time controls, not on RHP or any other online chess service. Master starts at 2200 but there are higher requirements for International Masters and International Grandmasters. Although, it isn't just about the rating. One must meet certain performance goals when making norms in special tournaments with other masters of the level you're aiming for. I think it's 2600+ for GM norms. For example, you can never be a GM if you just get a 2500 rating by beating up on 1800-2000 players.
