Maybe just an oversight in your analysis there, but shouldn't you raise the starting difficulty for your Jupiter calculations to something more like what it would be like in September?
See where it says 'time to delivery,' that uses the historical difficulty increase to predict difficulty out two months. It's true that KNC shipping in Sept will be an above average boost to the difficulty that will be offset a bit by people stopping mining with less efficient hardware but not that much. So, this chart actually represents a best-case scenario of sorts, with 130 days ROI being optimistic. This is yet another reason why I obtained a refund.
You used the same starting difficulty, when obviously an Avalon in the hand now is the only one of those two that actually will mine at that difficulty.
Well, again check the 'time to delivery field.' It's zero for the top calculation for the avalon, and two months for the KNC calc.
It would seem to throw off the whole calculation quite a bit if you were to start your Jupiter calculations at something like 50mil+ instead of where you have it now.
Naw, it's accounting for that using historical average, which may be high or low but at least is something.
To try and keep this on topic, I have an early order (47XX) Avalon, but they are 4 module, and I still see "Processing" as status. Are we noticing a trend that 4 module machines don't seem to have shipped yet? Might make some sense out of the out of order shipping...
Doubtful. I see no reason why a 4 would be delayed over 3's.
