I have not read through every page of comments, this may have been answered previously, if so I apologize.
So your chart is showing earnings of around .0015 BTC/day per Mhash on BetaRigs x11.
If I go on Coinwarz and punch in a gig's worth of khash in the x11 field (1,000,000 khash) the highest result I get is around 0.23 BTC/day.
You are reporting .0015 BTC per day per mhash, so if I was running a full gig that should get me 1.5 BTC per day. I understand your numbers are based on renting out your rigs, but are you able to explain why there is such a dicrepancy and how you are pulling in that much BTC per mhash compared to the Coinwars profitability charts?
