With my 360, I filled the inner ring during incubation, it would run between 40 -45% RH. Filling the outer ring for the final 3 days of incubation would bring it up over 80%, so I only would fill the outer ring with enough water to obtain 60 - 65% RH.
You can regulate the evaporation rate a little by opening/closing the vent on top.
You also have to figure in the amount of ambient humidity you have in the room where the incubator is located. AC and heating will have a huge influence on the stability of the incubator.
ETA - I kept the vent half open throughout the entire incubation period.
