Why is everybody so happy that they can produce and deliver so many units per day?

Don't you realize this is a race, and the best way to maximize ROI for customers is to sell batches, as Avalon did?

Just think: if KnC sells 1,500 Jupiters and delivers them quickly, when added to the rest of the network each one will probably produce aprox. 1BTC or less per day, and ROI will be unlikely. If they sell +3,000 Jupiters (which seems likely they will do), when they arrive each Jupiter will produce 0,5BTC per day or less, and ROI won't never happen.

Honestly, it's pretty scary to see them pushing out those numbers. Each additional Jupiter they sell removes value from the previous one. Kinda the same problem we thought BFL would have, but the reality ended up being that they are so slow delivering that actually their very first customers may break/even with their units despite the delays.
