Be sure you're differentiating between what Hucho has actually recommended, and what you recommend as pathways to low drag. He is by far not the only author to treat low-drag idealized shapes--although some others do at much more length--but all of them that I have read consider streamlined half-bodies as shapes which can be, in Hucho's words, "progressively transformed into a car." (He wrote this in a section which does not appear in the 2nd edition).

After reading my book, Dr Hucho wrote nothing to me about a template of any kind.
He was more concerned that I didn't have a chapter on wind tunnel testing than I'd completely missed this amazing template that Aerohead ascribes to him.
What you
will find in Hucho's book is this diagram:
No less than
five low drag shapes, all looking different! So which one are we to pick to help us in our modifications? Depending on that, the resulting mods will have quite different shapes! And how can that be so, when we've been told here for so long that there is only one template? (Or two, I find it hard to keep up.)
