Mahalo. I've been reading for what seems like hours and now I'm more worried than ever. I think I will just relax, set the eggs next week, and see what happens. With initial humidity 35-40%, candling/weighing/drawing air sacs on shells at days 7,14, and 18, and up the humidity to I'm not sure what yet but I'll know when I get there. BTW, did you get my photos of the blue coppers in PM?
I hatched several hatches of chicks last spring in an older Sportsman cabinet incubator. It didn't occur to me that the higher humidity would affect the younger batches until the end of my hatching season. I had very good hatches all the way through, even though I was raising the humidity about every week or so for hatches. So, I wouldn't worry about it too much unless you start having poor hatch rates.
