Rake and moving up

[spkid]

I was hoping that some of the more mathematically inclined could help me here. I know that if I move up from 2/4 to 3/6 my BB/100 is going to drop, but every big bet won will obviously be larger... I'm really still trying to understand the effect that rake has on expectation. At 2/4 thru 10/20 the rake structure at Party is the same. This means that the higher limit you play (within this range), the lower the percentage of rake your will pay - since the cap is $3 for all limits within this range. Is this correct? And how much of a difference will it make in the long run?


Thanks to any responses.
