Hey guys, I'm thinking about buying pokertracker. I just installed the PT4 trial and I am going to try that out for a while before I purchase it. Does anybody know the difference between PT3 and PT4? Is there any reason why I would want to buy PT3 instead of PT4? Also, is there a Luck Graph (Sklansky Bucks) on PT4? If there is, how do I get to it? Thanks.
