I've been sort of following
pieces of this thread and think this Kinch guy is like that - no
comprehension of Integral P dV and no wish to learn anything new.

The only "new" ideas I've heard in this thread are (in sum) "1: CFM does
not mean free air" and "2: Regulators don't waste power", both of which are
false.

If you don't believe my explanations, or don't accept them on the authority
of my engineering credentials, then there's not much else I can do to
persuade you.
