That requires an infinite ELO difference. Perhaps it only won a small sample of games actually played by you (e.g. 10-0 romp is believable, 100-0 is incredible but conceivable, 1000-0 is so farfetched as to be absurd) >(though novag >scorpio was slightly better against Genius 3 than that). > But CM8000 might indeed lose (a match) against CM5000, I was suspecting. For a single match, losses are to be expected even for a program with vastly superior strength (on occasion). That's why the SSDF plays a bucket full of games before they publish anything.
