I have 7 D3 on D3pool form Saturday 14:00 . Til now they make me 0.022 BTC that means , 0.0044 BTC per day , so one miner daily 0,00063 BTC wich are cca 5 /day.
It is not this a litle to less, because we talk about 8-9 per day?

You are right. Profitability has dropped significantly from a week ago when it started.
Personally I have often disconnections of my miners with this pool so I switched back to startpool which has similar profitability and 0% fees.
I'll be watching this pool though and if the disconnection issue is resolved and profitability is back to what it used to be I'll switch back.
