Hi, I don't think I claimed a rating of 2500 for PocketGrandmaster. We only played a few "rated" testgames versus human opponents. On the one hand PocketGrandmaster won twice from a > 2400Elo player (who had a bad day), on the other hand it only scored about 60-70% against a 2050Elo player with experience in playing computers (an author who writes for a computerchess-magazine). On an iPAQ 3660 (206MHz StrongARM) I estimate the rating is about 2200Elo (european ELO, USCF-ratings are usually higher). On a 400MHz XScale-Pocket PC running Windows Mobile 2003, PocketGrandmaster is about 4 times faster, which would add approx. 100 Elo.
