I've been mining on ghash.io since i sold off my ghs from cex.io to buy into my own asic hardware. At about 1.8 TH/s i've been pulling down about .034 to .036 or so per day. You said "best conditions" and by your numbers i should be getting 0.048312 per day. So if i assume NOT "best conditions" then should i think .036 instead of 0.048312 is reasonable?

also, something that might affect it - i've been mining on cex/ghash for about 8 months, and plotting/graphing the entirety of it for analysis purposes. The thing that i have found to be very intriguing is that when the difficulty changes, it really doesn't seem to have much affect on my mining production. like literally at all. with a slow decay in production over time, it's almost as though they linearize the decay that happens due to difficulty drop, and by that i mean make it into a constant decay rather than a stepped change like difficulty by adjusting based on the expected difficulty change which is amazingly accurate, especially the closer it gets to the actual diff change. my theory is that this is how they make their profit since they have a 0% pool fee. and honestly, i kinda like it... i'm ok with them making their profit in an innovative way outside the box of what everyone would normally assume.

if this is true, then it means what you should be getting vs. what you are actually getting would be different immediately before and immediately after a diff change.

whether i could and/or should be getting that extra 0.012312 per day, well, i have to do some analysis on that. when i'm not focused on building out my mining op i'll spend some time deciding whether to go to another pool and which one. but i like the fact that ghash is tied to cex, and the reason i got into cex was not specifically for the cloud mining but rather the commodity trading of ghs. regardless of the fact that their ghs is more expensive than hardware, regardless of how much i had, i was able to nearly double and quadruple it by seizing lucrative trading opportunities. because of that i was able to make thousands of $USD worth of bitcoin in profit, and sell out to by 20 s3's this week.
