Then it was all fed into a standard ratings calculator. However, the high ratings that you are seeing on the top-end personalities is due to a large bonus that is given to them due to the speed of your processor (under the fairly common assumption that each doubling of processor speed gives about 50 rating points). I would estimate, on your machine, that the Chessmaster personality actually plays somewhere between 2550-2600 USCF. jm
