You're right - I haven't tuft tested the before/after with the additional "fairing" aft of the skirt. I'm just making what I think it is a pretty safe assumption.

I think 3/4 inch is pretty good. You want the skirts as tight to the wheel as practical. Mine are about the same (actually the driver's side is tighter than the passenger side one, just from slight differences in my construction).
