I read where a cigar magazine smoked a cigar right out of a box, and rested the rest of the box, pulling one out to smoke every month for two years. The conclusion was most cigars should benefit from two months of resting, or longer if you have the willpower

As for cigars acclimating to a different RH, the rule of thumb is 1% change per week. It takes time for the humidity changes to reach all the way to the filler leaves.
