According to my PT stats, I should have gotten $85 in RB from Full Tilt last month. Instead they gave me $79.

Are the rake statistics in PT accurate? If so, why would the poker site have a different number?

It depends on the sites calculation of rakeback...
PT always calculates what you paid... but some sites calculate how many people were in the hand and they divide it etc etc.
I think some people just refer to it as NET and GROSS depending on the site.. FTP is apparently NET...

to quote something I got yesterday that somewhat explains this:
For these purposes the term "Poker Gross Revenue" shall mean the sum total
of all Real New Players' contributions to "rakes" the Real New Players were
involved in while playing at Our Site, less any credits, bonus or
promotional amounts given to Real New Players, chargebacks or any
uncollectable revenue attributable to the Real New Players. A Real New
Player's contribution to a "rake" shall be determined by multiplying the
quotient obtained when dividing the actual amount to a hand contributed by
the Real New Player by the total bet of each hand, by the total "rake" of
the hand in question. For example, if the Real New Player's contribution to
the hand is two Dollars ($2.00) and the total bet in the hand is ten Dollars
($10.00) and the "rake" of the hand in question is one Dollar ($1.00), the
Real New Player's contribution to the rake will be twenty cents ($0.20).

also.. short and sweet:

Thanks fellas. Guess I'll just have to let them keep my extra $6 for the month. But I really hope that when I get to stakes where RB adds up a LOT faster that I still aint going to be missing out on that extra 7%.

Poker Grapher has a rake calculator in it and for the sites that calculate rake as FTP and Pacific, i have to adjust it ny exactly 7% for it to be precise... My RB was $800ish so I guess it's not a hustle...

The best way to figure your MGR is to go to the PT tab that says "game notes"
Then click "get all".

There is an MGR column. Look at the bottom for your total. Thats the number they use to calculate your 27% or whatever youre getting.

Some sites that use contributed rake will be different (namely Prima).

FTP also subtracts things like transaction costs, purchases from the store and the supposedly "free" entry into the ironman tourney.

FTP is non contributed rake and my RB is always very very close to the figure that I get using the formula I posted. Its actually usually just slightly higher...not slightly lower.

Forget about the rakecalculator. Its an estimate. The formula I gave is exact.

If youre getting less than that number and have no transcation costs or anythig like that then you need to contact your RB guy. Remember though that if you qualify for the Ironman, you take a hit whether or not you play in it.

What is this ironman thing and how do I know if I qualified for it? Maybe I did and didn't even know it.
