What I have observed with regulators, almost all the regulators have a piston sealing on a plastic or polymer seat. With time the piston makes a mark on the seat and that is when it starts sealing instantly. That is when we say that the regulator has settled. You adjust the regulator either by moving the seat or the piston (incase of Fx regulator) which changes the piston and seat orientation. So the regulator takes longer to seal and again with some time start sealing quickly.
