I'm currently working on putting in some more volume just currently went on a 40 hour grinding sesh of poker in 4 days...When I have around 9 going its pretty brutal, I have them all set up and squared...but the biggest problem is my pokertracker numbers are overlapping chip counts etc, not causing me to make many mistakes although very irritating... I also know that the more I play the more problems I'm going to have making small mistakes/missing spots..etc... So if u could let me know what you use, and how you use it...Thanks DJ
