you’re not going to see the pressure change much coz, yes....it’s that small of a leak.Just look at the sealing surface on your reg. and on your tank. if you have a little "nic" it could coz a bad seal. other than that...o-ring. When I’m traveling I think about half the tanks I end up with are leaking at the O-rings, you kind of get used to it. at home I have my own tanks with a DIN setup, so no worries.
