So, by the time you get on a table 3-4 fish are gone and 3-4 new players are there. People looking for the high pot tables are probably skilled since they are looking for a loose table. At least 1 or 2 of the waiters are probably campers. By the time you get there the table dynamic has changed.

Any thoughts?
My sentiments as well. Not only are the spots typically taken by better players, but who's spots are they taking? They're taking the seats of the fish that bust out who contributed to the large pot sizes. So the fish are gone and replaced by rocks. Great table huh?

You also have to consider how the average pot size is calculated. On Party they count all money put into the pot regardless if the bets were called or not. I could go AI every hand on a $25 table and never get called but it would still list the average pot size as $25. Most sites calculate the average pot size based on the last 10 hands. One monster hand in 10 can greatly skew this number. Basically the average pot size isn't the best indicator of how a table will be. The % seeing the flop isn't the most reliable indicator either.

I just sit at tables randomly. Within an orbit, or two at the most, you should have a good read on the table texture. If it's favorable I stay. If it's not I just find another.
