When you buy a car, they advertise the MPG, that it won't rust for 20 years and of course, the price. How many guys did you see complaining that they bought a Mustang and they can't drive with a speed of 10 miles per hour and obtain the advertised MPG rate? How many of those guys did you see whining to FORD about compensation in price, because their product does not meet the specifications? How many guys are complaining that their car does not reach the 180MPH printed on the dashboard? They bought the Mustang, and they're free to return it or resell it.
Why would be the mining business different? Or any business for that matter? Everything changes when you reach understanding ..
What a stupid analogy. When a car manufacturer advertises 20 MPG, you can reach it by driving appropriately, and in fact you can exceed it quite easily. See
http://en.wikipedia.org/wiki/Energy-efficient_driving for examples.
Now, show me how you get an SP30 to run at 5.5 TH/s while drawing 2700 watts?
Did you really read what I've written, or you just skimmed over it?
You'll never achieve the advertised MPG at 10 miles per hour speed, no matter what your driving habits are and what wiki examples you find and throw at me.
This actually proves my point in a way. If two different guys read the same specification, they'll understand different things from it. I still don't understand why do I have to show you anything. For the conversation sake?
