2. 65% beads can really be anything from about 62-68%. If the beads are not showing as full of moisture, then you can assume that the humidity isn't really much more than about 1/2% or so above their set point.

Thanks for the help. I hadn't considered margins of error. I guess if both the gel and the hygrometers are running at the top of a +/- 2% MOE, the hygrometer could be showing something even as high as 69% and things would still be within "acceptable parameters."

yep. I've been there many times and have thrown away beads, dumped gel down the drain, and done all manner of insane things just because I didn't remember that the 65% number is followed by that dammed +/-

Mind you, I still make that mistake, but I have 30 years of "how could I forget that margin thingy" to fall back on.

I think that it was when I was hanging with MoTheMan one SoCal and he flat stated, "who cares what the meter reads, care about how the cigar smokes" that I finally got a clue.
