I’m happy that your setup worked for you, for the Cayugas, but unless they live next door to you, humidity ranges vary from location to location, so I don’t like to give exact humidity numbers for specific days.
Just my opinion, not trying to be argumentative. Folks have to dial in what works...
Did you monitor the air cells while incubating to see if they were losing enough moisture? 50% is usually too high for most of us. Unless it’s really dry in your area (I would assume most of Florida is fairly humid, but I could be wrong). So I would try running the incubator without any water...
