That's funny, I would have never thought that 11% would be considered a slight uptick in economy. From what i understand they did 3 sets of runs, one with the car stock, one with the car covered in clay and undimpled, and the last with the dimples. From what I understand, each set consisted of 5 "laps" I guess you could say.
I agree that a lot of what they do doesn't cover all the variables. But golf balls do have dimples for a reason, so why couldn't the theory be applied to something larger?
