    "An occasional hesitation every few seconds?"  That's not what I call
    real-time.

I may be naive, but I assumed when Barry Schein at Boston University
said that there was an occasional hesitation, he meant in the
(non-realtime) filling-out-the-questionnaire part of the application
rathern than in the real-time lung-test-data-gathering part.
