The pool is mining one of the losing coins right now. In the last 4 minutes that I have been watching, my 7950's could only squeak in 1 share between the zillions of new block messages. No way that will be profitable... Oops, just squeaked in another one while I was typing...
Yeah, we have a 25% reject rate. But the math says we're 3 times more profitable than LTC. It will be nice to know for sure though.
You are correct in this case. I should have checked the actual numbers before I made the claim I made based solely upon what was visible in the miner window. My bad.
Over the last 90 minutes, profitability is high, I am running at 0.07BTC per day per Mhash. Highest I have seen in 24 hours, and in fact triple the recent average.
Regarding past poor periods, try looking at:
Very low (essentially zero) from 2013-08-05 03:49:12 UTC to 2013-08-05 04:39:08 UTC
Very low (essentially zero) from 2013-08-05 04:59:07 UTC to 2013-08-05 05:25:15 UTC
Very low (essentially zero) from 2013-08-05 23:57:58 UTC to 2013-08-06 00:20:49 UTC
Since 2013-08-05 04:39:08 UTC, the run rate I have experienced has been running at .023BTC per day per Mhash.
