computeropponen: FYI, the BKR never claimed to be mappable in any way to FIDE ratings. It follow a rather simple rule that only result in a relative difference; the absolute value has no meaning. Typically, games where a lot of people play, the ratings spread out very far (see Ludo or Runs); games where only a small number of people play, 1512 is already a top-10 rating (Portuguese Checkers). That is just a consequence of the definition.

I agree that 2000+ in Chess is probably about a FIDE master rating. Which implies that we have about 155 FIDE masters plus cheaters here.
