Cool Side Preference?

I got my Pied on Friday and he hasn't been in the hot hide (that I'm aware of).
He last ate around July 3rd. Temps are 82F and 88.3F, I use a CHE on a pulse proportional thermostat.
Humidity is on average 55%. Both hides are identical.
What amount of time does your BP spend on the cool side?

Mine spend about the same time in both.
I check on things almost everyday and the last few days both have been in their cool hides. Beginning of last week they were in the warm side hides for a few days.
My temps have been fluctuating a little because we don't have AC and Michigan has been a little warm the last couple of weeks so that may have something to do with it.
