So I'll say again:
What I want to see is a section in any aerodynamics textbook that applies a template as has been so often been encouraged here. Viz:
- Show where there is separated and attached flow on existing cars
- Guide the shape of rear extensions
- Show how rear spoilers on sedans should be positioned and shaped
- Allow the assessment of the ‘aerodynamic purity’ of cars
As we both know, no such textbook or paper exists - and for good reason.
This is exactly the same logic as saying '225 section tyres are best' and then citing every car that uses that tyre as if it is sound evidence for the proposition that 225 section tyres are best.
What about them? None were developed using a template, or even a predetermined shape of any type. As for this list being evidence of anything, see my comment above about tyres.
Hmm, so overlaying a template over cars and saying 'it would be so much better if only it matched the template' is as nonsensical as it sounds?
Yes, and just as with the tyres, I've found that 225-section tyres give excellent results on many cars - something which proves absolutely nothing about 225 tyres.
Unfortunately the application of the template is just your weird theory - and I say 'unfortunately' because if it were as easy as that, gee, that would be good.
To others reading this, I'll say again. Don't believe me - just look in any car aero textbook and find those major sections extolling the value of a template. There aren't any.

1) I've given you a textbook on aerodynamics with the 'template' strenuously presented. You'll have to connect the dots which are screaming off the pages. You simply need to do the work which will then give the visual reference. Your tire analogy is asinine.
2) I've provided all the information necessary.
3) I've provided a list. Obtain the technical images as I have, and do the overlay comparisons.
4) I've addressed this adequately. I've provided the necessary materials. I can't understand them for you. It's not my problem. EcoModder.com members don't require your imprimatur to set land speed records, fuel economy records, or distance records. We don't need the imprimatur of any of your select panel of experts either.

If I'm going to insulate my attic, I'll be using the Owens-Corning/ USDOE R-Factor 'template' for my region of the country.
I'm not going to have a contractor come out 4- different times, adding 3-1/2-inches of fiberglass at a time, 'testing' and 'measuring' in between trips until I get the recommended 14-inches, recommended from the 'template.' Wasting the contractor three trips, and wrecking my finances in the process.
