Regulator short/long term storage.

Does the relative pressure differential (higher pressure upstream of the regulator vs lower pressure down stream) affect the longevity/accuracy of a regulator when stored/static for extended periods? I have only one gun with a reg but will sometimes let it sit for 1-3 weeks as I shoot other guns in my collection. As a precaution I time my shooting session to stop when the the upside pressure is equal to the regulator set pressure. Too OCD? =) Seems like the regulator would be happier if sitting idle with equal pressure on each side. Just curious what others do.
