Wow, that's some detail right there! I didn't take super-detailed notes. Basically, when I had a staggered hatch, I set the humidity to what was ideal for the chicks who were hatching--a bit higher than normal, in fact, to compensate for opening the incubator to hand-turn the setting eggs. I didn't notice any adverse effects on the air cell development of the eggs that were set, and when the eggs that were hatching were done, I let the incubator run "dry" for a while to compensate for the period of higher humidity. I had a very good success rate--in the staggered clutch, I only had one or two late quitters, and one of them was obviously due to problems with the egg itself.
Temp was kept steady at 100 F at all times, though they would of course have dipped when I opened the incubator to turn eggs.
