[pete fabrizio]

i tried figuring out an autorating scheme and it was pretty useless. I simplified it and said that anyone with vpip over 55 is a fish, under 25 is a rock, preflop PFR below 10 is passive, above 20 is aggressive, post-flop AF below 2 is passive and above 3 is aggressive. and any vpip above 40 is probably too loose. but even those general parameters seem to have exceptions, since there are some pretty good 20/2 or 50/12 players (and at the higher limits some pretty good 55/30 types) who don't fit the 30/20 mold. broadly i think the rating system is pretty useless, since you can get a pretty good sense of someone's style (though not necessarily their quality of play) from vpip, PFR and aggression factor (especially if you look street by street) without needing a little icon to summarize it.
