Ok, so I've been playing on pokerroom for a good bit and come on here today and hear about the new rake structure. I made an excel sheet with a crappy excel chart that plots the pot size on the x-axis and the rake (new and old) on the y-axis. I heard some people say that at the low limits the new rake structure is actually better, but I don't think that's the case. From 16k+ hands I have in the .25/.50 (always choosing juicy tables), pokertracker shows the average pot to be $4.9 which is very close to the breakeven point for that limit but it still makes the rake higher. I think the new rake structure is actually lower given the avg. pot sizes of higher limits (ie. $1/$2), but I'm not really sure since I never play there and have no pokertracker data to support me. I uncluded the excel sheet...all you have to do is change the value of the "Big Blind" in cell A3 and look at the graph. Check the "Avg. pot" in pokertracker under the "summary" tab and see whether your average pot lies in a region where the new rake is lower or higher. I know it's higher for .25/.50 and .5/1 but I'd be interested to hear about the other limits.
