my one question, does anyone have the experience to say whether or not this amount of a leak should show bubbles?
Probably not as that isn't much of a leak. On the residential side its not a leak. I think the only way you are going to find it is 1) isolate/ disconnect all the appliances and pressurize to 2 psi with air then re-soap or 2) locate/ borrow an electronic sniffer.
Personal experience: I had a natural gas leak in the furnace/water heater room of my previous house. I soaped all the plumbing multiple times and couldn't locate it. Finally got mad and brought home my sniffer and found it in about two minutes. Tightened the nipple and all is well.
