For the 20+ year old desktop in my office I run 72% Bovedas in the Winter and Summer when the HVAC runs frequently. Both tend to dry things out pretty quickly. Spring and Fall the HVAC doesn't run nearly as much with my office being downstairs and only a third the number of windows as upstairs. During these times, I step down to 69% Bovedas. Had to do a battery change or I would be able to show you a bigger graph, but this is the last two months and I believe I swapped 72% for 69% packs two or three weeks ago when I started getting 70% + RH alerts from the hygrometer. You can see the RH is slowly coming back down in the target range with the lower RH Bovedas. I think you will find there is no single right answer and each humidor will have it's own preference for you to discover.
