There is no pressure drop when there is no leak. If the pressure is less than 50 PSI, it's leaking. Put a little dishwater detergent in some water and paint it on the joints with a paint brush. It will blow bubbles where the leak is.

Leaks can be quite common. Proper maintenance is quite necessary for everyone. It is essential that people are able to find good quality services to deal with those leaks. Well when pressure is given on the leaking area, things might change.

Call the gas company and report a leak. They'll bring some specialized sniffers and track down the leak.

You might get charged for it, or maybe not.

Understand that I have no clue as to if this is a good idea or not. I know nothing about plumbing but my wife is paranoid about gas leaks and everytime she calls, they come running.

agree zero pressure drop should be standard. Interestinglyu enough the licensed HVAC contractor turned system over meeting the 10# for 15 minutes criteria, but certaintly not meeting the no pressure drop criteria. found leaks. tightened. holding 15# for five + days.
