Also, only 7.2% fee is ok I guess, but it would be better to write 7.8% rather then '2.2% less then Deepbit'.. might try it though..
If the fee is 2.2% less than Deepbit, which has a 10% fee, that makes a 9.78% fee.
10 × (1 - 0.022) = 9.78
Read the messages from dinox. He never talked about the fee, only the compensation (to the miner).
