I did the tuft testing, with and without a cardboard / tape mod to smooth the grill and headlight area, and I agree with you. The flow looked the same either way. There was a bit of a turbulent spot in the lower middle of the windshield. Perhaps because of the windshield wipers.
So, my question is, should I just focus on grill blocking and air dam? The idea I drew earlier included a clear plastic transition smoothing from the bumper to the hood. That seems unimportant now.
My thinking is that the point of stagnation is the most important result of the air dam. Ideally I want it to start at the existing point of the bumper and slope forwards to get as much air up and over the car rather than under it.
