Yes, I think following a template in the mistaken belief that will get you a stellar outcome is wasting people's time. Far better that they do some testing and find out what is optimal on their cars.

As for your examples, as I've already said - if the extension has attached flow down to a smaller wake, I'd expect pretty good results... template or no template.

To make it categorically clear, I think posting a template for car shape on a discussion group and very strongly implying that it is the best shape for people to follow (no matter their car) is misleading and wasteful of people's time.

It might have been helpful in a past era when testing panel pressures, drag and lift were difficult, but that is not the case now.

Keep researching.
