I have been mining on this pool for a while now, but recently switched to the X11 pool because of diminishing profits. X11 seemed to be a lot more profitable, based on the estimated btc/day. But now that I have been mining for a week or so, it seems like the estimated btc/day is off by quite a lot? It's telling me I should be getting about 0.0014 a day per MH, but I am putting in more than twice the amount of MH's (this is reported correctly on the site too) and I am not getting 0.0014 a day by a long shot. In fact based on my last payout, the amount of MHs and the time it took to gather it, my calculations show I'm actually getting only 0,0001485790625 BTC/day, which is TEN TIMES lower than the estimated value.  I've got no HW errors and a very reasonable reject rate. What's going on? Is the estimated btc/day counter just off, or is something wrong with my system? I haven't mined x11 before so I can't really compare to anything.
