However, there were only five personalities that were used in the test: Chessmaster, Josh Age 9, Willow, Sonja and Skippy -- basically personalities with ratings of approximately 2500, 2000, 1500, 1000 and 500 respectively. With these five "real world" anchor points, the ratings data probably became a fair bit more accurate, but I would still venture to say that some, if not many, of the personalities are between 50 and 150 points off the mark. As for it being a selling point, I'm sure it's mentioned somewhere on the box. ;-) jm
