am i figuring my rakeback right?

[teamdonkey]

my payment for a month was only about half of what i figured it should be, just want to make sure i'm calculating it right.

total rake: $3269.22
average players per hand: 5.58
rakeback: 27.5%

so i should be getting:

$3269.22 * 0.275 / 5.58

= $161.12

yes? or am i missing something here? I got some bonus money for the month, but since this is at Absolute i don't think that takes away from my MGR.
