I would argue that Audi put the recessed points on there to give more rigidity to the mounting point. not for some 'perfect' flow attachment pattern.
Let's look at this logically.
1. Audi (and all of the top line mfgrs) are making HUGE strides at (for lack of a better term....) ECOMODDING.
2. whether it's on/off engines from BMW 3 series or regen brakes from Buick, companies are pushing the envelope to gain 1/10 more mpg.
So you have to ask, why are the recesses ONLY at the mounting points??
And not evenly spaced across the surface??

Good point. Plus, if they hung down, they would catch junk.
