I just remembered the guy writing the book on ecomods had a section of why roll down test do not work.
I don't remember what he thought was better, but it's in the later half of his thread.
EDIT: It is a video I have not yet watched, see link below post #78.
Writer seeking examples of tested DIY aero mods for book
Does coast-down testing work?
