APs can also be misleading as some sites update them infrequently (Stars), update them after practically every hand with a short sample size (Party?), or simply lie (Pacific). But it's still my main criteria. I'll tend not to LEAVE a table with a low AP if I feel there's a good chance of me winning (good handle on an opponent, a feeling the low pot sizes are due to a string of poor hands etc), but when selecting tables it's generally all I look at, with flop% being the only other area that interests me. I play too many tables on too few sites to be much more selective than that.

obv good table selection is

1) look for "Anders"
2) repeat

Yep, used to be my MO at Crypto
