Is that what you mean?

Determining the optimal angle for a boat-tail (or any body extension) cannot be ascertained by looking at a template.
No predetermined shape can be used to do any of the following:
Guide the shape of extensions to cars, to guide the heights of spoilers, to assess the 'aerodynamic purity' of shapes, to determine where there will be attached and separated flow etc, etc
If it were all as easy as that, gosh that would be good.
