Why would I try to find the exceptions? Most fastbacks generate more lift than squarebacks and notchbacks.

2) ditto for 'wake size' attributed to drag, as examples of larger wakes with lower drag exist in the public domain.
Yes, but why would I try to find these exceptions rather than using as examples those which are most common?

3) and as to the tuft testing, and in light of the Porsche 911, VW New Beetle, and 2010 Audi A7 Sportback, there's a clear solution liability, by virtue of misinterpretation of observational tuft alignments, should the individual confuse 'downwash' phenomena with 'attached flow.'
This is a difference that you have just invented. Attached flow is attached flow, whether it is caused by downwash or not. I have already quoted the head of Jaguar aero in support of that, but as always, you believe that you are right and the true experts are wrong.
