Guys sorry for bother you, but could someone pls explain me the earnings on BTG?  

Have 1920 h/s and after 3 days of mining getting just 0,06182091 BTG...

Calculators says it should be something like 0,054 - 0,055 BTG day...

Switched the pool and same result, after 2,5 days got 0,0565 BTG...

What im missing?

Thanks for any input
