Genesis-mining, payout accurate or not

Hi All,

I started a mining contract with genesis-mining on 08-9 for 0.25TH/s

and then later upgraded to a total of 1.3Th/s

According to the mining profitability calcs out there I am supposed to make around $1/day (after deducting the maintenance cost)

but I'm only getting about half of it.

Any Idea whats happening?? Or am I missing anything??
