I would like for OP to explain this:

My referrer is claiming to pay 50% bonus back to his referrals. Yesterday I took a screenshot of my last free claim for the week for a total of 3460 Satoshi. I have been active claiming at least once per day. According to the bonus return of 50%, I should have received today, before the payout, an additional 860 Satoshi but when I logged in, the kickback notice said that I only received 761 satoshi. My first thought was that my referrer lied and set his return bonus to 44% instead of 50%.

But then he showed a screenshot of what shows me being paid 872:

So then I went back and double checked my numbers:

What I had Saturday night:

This is the notice of the referral bonus kickback:

Which brought me up to this:

The 761 that I see conflicts with the 872 that my referrer sees. But then I realized that the difference between my amounts before after the referral return bonus did't look right: 3460 and 3812... that is not a difference of 761. 3812 - 3460 = 352. Freebitco is claiming that I recieved 761 satoshi when in fact I only received 352.

OP, please explain this.
