Where are you getting this average VPIP figure? From a Poker Tracker game time window, right? This may be obvious to you, but one thing that can happen with that method is that if you've got one tight aggressive regular at the table, on whom you've got 1000 hands, and a bunch of new players on whom you have almost no hands, the listed VPIP figure is weighted by the number of hands you have on each player. You'll find that the tight aggressive player with a lot of hands in the database is dragging the average VPIP way down.

Or are you mentally averaging the VPIPs across players, regardless of number of hands played? I don't even do this, I just sort by VPIP and look for four or more fish in order to feel happy with the table.
