Hi Ron -- great tutorial, very nice work, but I just had to comment on this.

Do you have some magic way of sensing pressure drop? Reason I ask is that I don't see a gauge hooked up, and even if that Schrader has a pin in it, hooking up a hose and gauge normally results in a small loss even with self sealing couplings (or at least mine do). That small loss could be interpreted as a pressure drop, especially considering the small volume being looked at.
