Payouts are low due to ZenPool being lower than it was a week ago.  Payouts are low because BTC price is down, which directly affects your fees.  However, ZenHashlets, should most certainly not be hashing at a loss.  As of right now, 1MH/s ZenHashlet will earn 0.00037521BTC.  The $0.08 fee with BTC at $350 is 0.00022857BTC.

Yup, you're paying 60.92% in fees, but hey... it's not a loss!
