It's 1% per week on average, but only when making relatively small RH changes (like from 70% to 65%). That is also the rule of thumb for the humidity change to make it all the way to the center of the cigar.

What you really don't want to happen is for there to be a humidity shock to the wrapper, which can cause the wrapper to crack and split.
