Rake on pokerstars and PT3

[Codearmani]

I dont understand how the rake can be different from what PS says.

They say that i get 5,5 VPP for every 1$ in rake. But when i calculate the rate compared to the VPPs i actually get, it is much more like 4.5 than 5,5. How can this be? Can rake be adjusted or?

That's because they use Rake Contributed - that's the number you should compare to.
