No, I don't think so, but I've never really thought about it in those terms. VGs just energise the boundary layer and so potentially give better flow attachment where separation is occurring.

No idea. Testing is king.

No I don't think so.

Yes I was employed as editor at AutoSpeed for a long time. The very brief mention I made there of putting AirTabs under the car was very anecdotal - and was stated as such. There's far more detail, testing and analysis of VGs in my book.
