Then it really shouldn't be too much to ask for someone knowledgeable in jet engine performance analysis to define these terms for us, should it?

(Then, for example, we would be able to tell if a statement such as "braking effect in reverse thrust is due to inlet drag" is just a tautology, or if it has substantial content)

And how is "inlet massflow" defined?
