RH difference?

I keep my cigars between 68 and 70% and always have a great cigar burn. I also dry box them for a day at least before smoking. This routine gives me optimum smokeability. Everyone has their own routine as to how they like their 'gars',,,I don't like a cigar that has a 60-64 RH,,just burns too dry for my tastes,,,but that's me.
