maybe theres something to this?
Someone can describe a better test than me, but I would do this, with and without the skirts :

1 - Find a hill you can coast down in Neutral that has a 45 MPH speed limit, and won't put you over 50 MPH (so no one can get mad at you for speeding) max on the coast. Maybe this means starting at a lower point down the hill. The hill will need a nice long flat section of road at the bottom.

2 - Start from the same start point each time. Coast down to a rolling stop as many times as it takes to get a reliable average for distance, max MPH, and time. The idea is to show repeatability.

If the skirts work, all three of those variables should be greater than without the skirts.

I think the only problem is finding that hill.
