You've disagreed repeatedly with that description, one which Dr Wolf specifically endorsed.
Aero of Road Vehicles 5th Ed would probably cause me to add a bit more to that description, were I writing it now.

The sticking point for me is, the use of the term 'attached flow' to describe the original flow condition on the 911's rear contour.
Whatever transpired between the two of you is none of my business, but if Dr. Wolf actually agreed to the use of 'attached flow', as proper nomenclature, then I cannot abide by that.
' Downwash' yes, 'attached flow' no.
