I have only mined for just under 7 hours, 6 and a half since a block found iirc on updamoon and have only made around 2/3 of your 7 per k per hour.
Perhaps it's a little low but then again it's too short a mining time to tell for sure as well, i'd think?
The pool hashrate has dropped to around 200MH/s and the network has increased to 560MH/s. updamoon was still reporting 460MH/s for a little time while steady was reporting .56GH/s but they are the same now. It's just that the network hashrate is fluctuating wildly which won't help
