popo12..Analyzing your past mistakes is something that every poker player who shows long-term profits does, from what I hear..That is one of the things I see over and over anywhere I read about poker. If you do not analyze your play; than you will not know what you are doing wrong, and you will not know what to do in a similar situation when it arises. Software to analyze your play won't make you a winning player, but analyzing your play will definitely help you realize your weak points. So why would you not want a program that organizes all that info for you and displays it how you want on a HUD or in graphs or whatever. I should have gotten one long ago. A lot of players use them, I dunno exact #'s tho. Anyone who multitables most likely uses one, as well as many other players.
