If your redline is going up at the micro stakes your probably blowing hands out of the water you beat. Getting people to fold before showdown when you have the better hand is not a good plan. If you are getting to showdown around 24-28% and winning about 50% give or take then you will see the redline come down. All the numbers actually need to work together, VPIP, PFR, aggression and showdown stats. posting your PT3 or HM stats on the first page will give ius better questions to ask. Nobody will have diffinitve answers but there are parameters.

And yes 2K is small as a sample, but I still don't think it should be going up too often although possible. 5K is better and 10K shows some issues with your stats.
