If your sticks are on the wet side when you put them in your tupperdore, and your bovedas are fresh, or getting a little saturated, there's no room left in them to take in more humidity. The cigars will remain over humidified. This is my experience anyway. I took 2 of the 4 boveda packs out, let them dry out for a few days, then put them back it. The hygrometer indicated the RH returned to where it had been.
