FT signup bonus deduction question

[cmstaab]

I realize that Full Tilt deducts bonuses from MGR, but I have a question about how they do so.

For example, you rack up $100 of MGR in a day and in that time clear $20 of bonus. Is $20 taken off of your MGR leaving you with a total of $80, or is it some type of convoluted formula?

Thanks in advance.

In your example you would get 27% of $80.
