I'd call it a revenue opportunity. Visors would help trip time, but if a water
delivery calc indicated a higher air pressure decreased transit time as well
the clapper shut.

I would check to make sure that the air supply to the DPV is working as it
should. The time to trip should never be that long. Is the by-pass open?
Sounds like the make-up air is supplying to much air. The make up air needs
to be restricted. The supply line

Was it a Victaulic #756 or #768? Look closely at the differential piston if it
is a #756 some time they stick.

I don't believe their is any reference to how long is too long except in
13 (pre 2010) where a system of between 500 750 gallons is required to
have a QOD if the water delivery time to the inspectors test exceeds 60
seconds. I think there is a presumption that a system of less than 500
gallons

From old time experience there may be obstructions at the dry inspector's
test valve or other that is obstructing the flow of air. From insurance
inspector days anything over 3 minutes needs further investigation. I would
have called 15 minutes a failure in the 60's and 70's.
