I think you are right regarding the least airflow under a body is best but at some point assuming the same ground clearance are you not increasing frontal area if you block off all under flow. It could be this is an advantage anyhow. If the larger frontal area is offset by reduced drag. I have not heard this spelled out yet. Thoughts?
