The SAE Paper on the Audi A7 Sportback also had all the proper physics, and perfectly described how the 911 body failed attached flow, induced the vortices which induced the downwash, which gave the illusion of 'attached' flow, small high-drag wake, along with the persistent, long-lived, pseudo-Jaray longitudinal vortices/ high vortex-drag.
Um, you haven't read the SAE paper on the A7. You are going on my description in the book which was all about different rear diffusers for different body shapes, and mentioned the rear spoiler only in passing. And it didn't mention the 911 in the paper...
