That's the sales line, but it's illogical. If you want progress, you agree to buy one of any new design, paying the full development cost plus profit. They certainly won't be cheap, but you're just buying the one, and are mai nly paying for the R&D. If instead you buy 100 or 1000, you pay all those c osts plus a big pile of wasted money on the other 999.
But it's politics, where any bull flies.
