I know exactly how you feel! I'm on my first hatch, and I started at 50% humidity after some light research into basic requirements for incubation. Then I read about dry incubation, and how many people have problems with chicks drowning after internal pip because the humidity was too high. So I stressed about the humidity being too high! I started to let my incubator "dry down" to do a dry incubation. But then I got stressed about the humidity being too low and shrink wrapping the chicks and killing them! So, since this is my first try, I decided to go somewhat in the middle. I add water when the humidity drops below 33-35% and try not to let it get above 40-45%. I feel least stressed when the humidity is hanging out around 40% although really it's just because that seems like a nice number between dry incubation and the 50% humidity that I read when I first looked into hatching, I have no experience to base that on.
Keep an eye on your air sacs. Someone here posted an excellent diagram of where the air sac development should be on days 7, 14, and 18. It really helped me relax about my humidity because my eggs seemed to be developing right on schedule according to air sac size, so I feel that the humidity has been just about right. If your air sacs seem too small, decrease the humidity. If they seem a bit too high for the gestational age, increase it a bit. Then cross your fingers and hope for the best like I'm sure everyone does their first time hatching. Let's see if I can find that chart for you.
Here it is:
