I'd ditch the analog and get a digital
I leave it in the bag (I actually use a tupperware dish for better seal) for 24-48 hours and if it does not read 75% then I adjust accordingly. I put a small piece of paper with +1 or -1 (or more depending how far it's off) so I know when I look at the hygro where it actually is reading
