At this point, I don't know if you're getting what I'm talking about or
not. My whole point is that the inertia of the gasses in the port are
relevant, and that you want to keep them moving as fast as you can for a
given CFM.  Perhaps I should have said no air flows _past_ a closed valve.
Could you not have gathered that from the context of what I was saying?
Perhaps not, and I have no proof reader....
