Highest ratings on RHP

Why are the highest ratings here on RHP all below 2500?

On another server which I play, the highest ratings are 3100+. Is the rating system different here (the other one used is ELO (on the other server)), or is it just the level of player (no offence)?

Or, is it to do with the fact that this is correspondence chess?

Smaller user base and less total games played.
