Basically my pictures suck, so its hard to fully see the mounting environment for this panel. The front edge is hidden behind the body's underside where it curves around the rear edge of the foot room for the rear passengers. Its only open a little bit in the middle where I mounted it below the exhaust, but even that is higher off the ground than the trailing edge of the front skid plate. So its hard to say how much airflow that part is even seeing. Sealing that part would be tough.

Christ, I get what you are saying, but I already have a front skid plate / belly pan. When I jacked the car up to put this new panel on, I hadn't yet decided whether to mount it directly behind the front skid plate and continue that panel, or go back to the rear axle like I did. I chose the rear because it appeared a much more turbulent zone.

If I throw a new front valence/lip on there, I will definitely seal it back to the front skid plate for full smoothness. My thought was that allowing less air under the car would lessen the drag of any wake or turbulence effects still occurring under there.

Bob, why does it spin the direction it does? Rotation direction seems pretty arbitrary to me. Factoid; anemometer sizes are measured in units of "crow".
