If you were to slice the template vertically at the 0% mark and insert a rectangle (of any width), the drag coefficient would go up due to skin friction, but you could still use the template to guarantee attached flow, right? So a bread truck or a minivan with a boat tail grafted on the back would do okay, though not as well as the same treatment applied to a Prius.
That's it! At the back,that's your zero-point,and you're just doing a boat-tail as Mair did,or NASA,or my VW bus.
