Current daily mining profit for 1 TH is 13021 satoshis, my last five payouts on hashflare were around 14500 satoshis per TH.
Are the pools just lucky atm or is there another reason for that?
I doubt they finally pay the fees additionally to the block reward.
I noticed this, I'm receiving more too... probabily they are paying some part of the fees.
A lot of people complaint about this, and it's fair pay all the block reward anyway.
