That reminds me of a
rear spoiler on a car I once raced against:
The car was very fast (low drag) and hard to draft. If I remember correctly, the driver/owner claimed that the saw-toothed spoiler made more downforce and less drag than a spoiler that was the height of the bottom of the saw teeth. His business is data acquisition systems, and his car is fully instrumented to measure such things, so I tended to believe him.
Also, when I saw the car, I believe the spoiler was about the same height but I remember the teeth as being a lot more prominent (taller), fwiw.
