So, it is now 12 hrs later and my hygro is only reading 65% opposed to the 75% expected. Now, I know that hygro's are generally off by a few percent, but is this large of a deficit normal?

(It IS an analog hygro -- the one that came with the Savoy humi...)
I sealed my digital and analog hygro in a ziploc bag with a Boveda 75% humi bag. Hours later, my analog read about 60% and my digital 65%. I tried it over and over with different bags and different settings. Looks like both my hygros are way off
