The stats provided on this site are completely wrong. I even checked my personal stats and they were way off. I would not tell anyone to use this site to gain an upper hand on the competition. They advertise a tool to "spy on other bidders" but I'm sure the information on that is way off too. I do however like their forums where you can talk to other PA users.
I was told to go to this site because they had statistics on bidders and sites. It turns out their stats are not correct a lot of the time. They say in a disclaimer that the stats are basically used for entertainment purposes only and that its our job to determine the validity of them. I wish they made that clearer because for a while I was in a heated debate with a few sites over their win limits and how certain users were able to exceed them. Turns out, the stats on this site were just way off.
