If your temps are accurate at 90/82 and 80 what ever you are doing is fine there is no need to change it if you are getting those temps correct. (assuming the thermometer is reading correctly you might check it against a second one.)

I like to have similar sized hides your first post mentioned a single hide. I assumed you had only one. They are individuals some do come out during the early morning (6-10am) It is the type of motion is it lasy poking lots of tongue flicks or more jerky 'frantic' with few tongue flicks the later is stress the former just exploring.
