Do you have some magic way of sensing pressure drop?

That small loss could be interpreted as a pressure drop, especially considering the small volume being looked at.

Your right Michael. My wording and picture arrangement were off in this post. I already had it hooked up to my gauges and did a pressure check. I also filled my kitchen sink and did a bubble check.I never trust Schrader valves. They will let you down.
