I have found that when you join a long waiting list (like 8+ deep), by the time you get to the top of the list, the reason everyone joined the list in the first place will often be long gone. Paradoxically, if you join a table that is nearly full, or has a very short list, you often find that the players-per-flop stat was misleading, because the table was short-handed and the stats haven't caught up yet.
Screw all this table selection crap! Rush Poker, here I come!
