Anyway, I think the main reason why it's so hard to compare RHP and OTB ratings is the wide range of time used per move on RHP. Even with people of equal skill, one person might have a huge game load and only take seconds on any one move, while another person might only have a few games going and take hours on each move. ...[text shortened]... games or they only have limited time for their games due to other day-to-day responsibilities.
I think the recent comments are right on. You can lower your correspondance rating from what it could be by making moves too quickly (which also relates to loading up with a lot of games). For myself, if I made 30 sec moves on average, I bet I'd drop 200 points. (I'd estimate I now average 3-5 min on moves that matter.)
But, going the other way, I think you can reach a level (for me personally, I think I'm there) where it doesn't matter much if you spend ~more~ time. Less about blunders and more about failing to recognize a strategy that a more advance player employs early enough. For this, I think whether you spend 3 minutes contemplating the move or 10 min, if you don't see it you just don't see it.
I think it is really a matter of personal preference. I am happier carrying fewer games but (trying) to make them of a relatively higher quality. But, I can also see the fun in playing with a more blitz-like mentality.
Bottom line, because there is such variety in the way peeople choose to play at the site, I think it is difficult to relate the RHP ratings values to other rating systems.
