I assume you are using a Lumicon tank.  I have a similar leak with my
homemade tank.  With my rig it takes five days to hyper Tech Pan.  I start
out with 15 psi and it bleeds down to three after five days.  This has been
going on for 20 years and I have no problem with the resulting film.  The
evolution of my needed hypering time probably takes that leak into account.
If the leak stopped, my hyper times might need changing.
