How long does the lid have to be open?

[Smokin Low]

Hi Gang

I have a Milano (75 ct) humidor. I have some beads. I have an accurate (75% salt test) digital hygrometer. I have some cigars. I have fluctuating RH readings.
I tend to open my humidor daily; cause I just like to look. Some days it will be at 65% when I open it and if I happen to open it again some hours later it may be at 60 - 61. Do you think this normal or do I have a problem with my humidor. I would say that it would usually be open for up to 10 seconds at a time and maybe 30 seconds total per day.

I have not done the flashlight test yet and I have more than enough beads for this size of humi. The seal is tight, takes some force to open.

I suppose I could just leave it alone for a coupl of weeks but I just want to see them little beauties.

Thanks for the help.
