UB MGR discrepancy. Anyone else???

[WillyT]

I know UB switched to the contributed method for MGR contribution, however, there are two different listings of how that is calculated which may be relevant in what follows.

Also, I know they now charge US players a fee of 15% of their MGR to be deducted before getting rakeback. That is, the MGR listed on my affiliate's page for me is my MGR less 15%.

Even considering this, my total rake paid for the month is over $2700 yet my MGR listed on with my affiliate (TITN) is $2107.

I play mostly limit hold'em with about 1/3 of my hands on the month being HU.

I cleared less than $100 in bonus on the month and UB deducts 25% of bonus clearings from one's MGR.

Anyone else have any data they can share? Is there a program that can calculate my contributed MGR?

Thanks,
Bill

p.s. the two different contributed MGR calcs are from TITN and RTR. TITN claims generated revenue per hand = (total money contributed to pot)*(rake)/total pot) whereas RTR claims if you contribute even 1 cent to the pot your get an equal share of the total rake added to your MGR.
