That's up to you. If you are going to be hands on, opening for any reason, I would add a wet sponge or cloth and push it up past 65% if possible. I shoot for at least 70% and use sponges in my bator.
If you are going to be hands off, leaving the incubator shut for hatch 60% can provide enough humidity. Yay! For pippers, congrats and good luck!
Depends on your bator too... but I keep a shotglass with sponges cut up in it with distilled water inside. I also keep a 2 inch funnel with aquarium tubing. If I need to open, I put that through my air vent and can quickly drop additional water into the bator. My basic start is wells filled with paper towels laid across to wick.
Glad you are feeling better! We have to catch up!
I'm still getting used to it too. Glad your feeling better. I didn't miss you at all 
My grandson Oliver two months old now.
Hoping so... after a couple hatch...
