Wow, 600 bitcoin for 8 units? That's ~500gigahash/sec. ~23% on your investment, which isn't bad if the diff pans out, for sure, although the amount of time needed to achieve ROI based on expected diff increase of 130 days is why I pulled out, because if KNC ships these may never ROI.
I'm kinda surprised you didn't ask for a refund given how tough ROI looks right now. I guess we all have our different assessments of how quickly difficulty is set to increase right about now.

Well, no doubt you know what you're doing! I wish you luck, sir

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?
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. 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.
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...
