How accurate is the RHP rating system?

was just curious how accurate the red hot pawn rating system was. i ask in the debate forum because i couldnt get a straight answer in the general forum. Compared to maybe Us chess federation

I know Living Legend said he's rated about 1900 OTB compaired with 2100 odd here. I haven't completed enopuph OTB games to tell you how accurate mine is, though i recon it's probably about right as it is the same everywhere else that i play as well, with a couple of exceptions on sites with a low number of users.
