... I'm not talking about software you use while playing(HM2, Pokertracker 4, Holdem Indicator)....
Many people have a strong missconception regarding the proper use of these softwares and particulary PokerTracker 4 (since is the one i use) and its real value/impact towards improving your game. I┤ve being a long time PT4 user and im one of the most active members of its forums and i know realize the value the program has if you use it properly to improve your game.
But to ask your question, for me personaly have been flopzilla by just running down hundreds of spots and developing a solid hand reading hability that have helped me abused and exploit villains postflop more profitably.
