am i figuring my rakeback right?

[teamdonkey]

i dont know what a "standard calculation" is, but my data is from the right site and date range. I got this email from AP in response tonight, but don't know what to make of it:

Here is the how we would calculate your Rake Rebate:

Total Hands: 7974

Total Raked Hands: 5581

Real Rake Contribution: .06

5581 x .06 x .275 = 92.16

$92.16 is what i got paid for the month. I have no clue what "real rake contribution" is though. I do know 92.16 isn't 27.5% of the rake from only the pots i won. Not sure how this is working.
