Rake Percentages

[Limit_Donkey]

I tried to use the search but no luck so I will post anyway.

I was having a look through my pokertracker database and thought I would see if the rake paid changes much between sites.

Here is what I found:
Figures based on at least 5000 hands 2-4 6 max Limit:

Pokerstars = 0.099 cents per hand
Prima = 0.11 cents per hand
Fulltilt = 0.08 cents per hand

And also 3-6 6 max limit based on at least 5000
Pokerstars = 0.17 cents per hand
Fulltilt = 0.157 cents per hand

Now am I missing something here or is Fulltilt by far the cheapest place to play and with 27% rakeback on top.

The reason I looked into this is because I had just started playing lots of 6max limit again and thought about trying to work my way up the pokerstars VIP ladder, if these figures are representative then I would be giving away heaps of money by playing on Pokerstars rather than Fulltilt.

Can anyone confirm this or am I missing something?
