I reported that Dr Wolf was in agreement with the description in my book on how the rear spoiler of the Porsche works. Attached flow without a spoiler, then with the spoiler, a stronger negative pressure gradient (higher pressure in other words) that causes flow separation where previously there was none.
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.
