Hi ... I started mining since 1 week with antminer D3 17GH/s, all week looking good on earnings except Today Sunday's payout is 35% less than last Monday. Is this normal or something went wrong? appreciate if anyone clarifies me on this. Bye the way i am new to this mining started mining since 1 week only. I configured diff as 16.

Pool1:
stratum+tcp://stratum-us.granatgas-pool.info:1111/#xnsub

Frequency set to default.

Thank you!
