I've used the trial version and have yet to see one account for tournament play where my total "net won" is correct. Regardless if my account is on ipoker, Ongame, or Microgaming -- it shows every single account as a losing player (Not ONE account is correct). This is the most frustrating part of PT3. With over 600k MTT hands and god knows how many MTTs, I can't possibly remember all the results to manually enter them in. On Microgaming tournaments with a buy-in, it shows tournaments with buy-ins as a freeroll (no entry fee). With freerolls, you have to enter the results yourself. Most SNG P&L is correct. Coinflip-type tournament results is a complete mess.
PT3's cash game graphs and HUD stats seem to work fine. But if you're looking for accurate P&L for tournaments, look elsewhere.
