I understand all sides here but this just required a simple answer.
Is he eating, pooping, and shedding normally with good temps being offered? If so, job well done. If not, then maybe its time to start questioning your setup (ie. Hides, etc) Unless your snakes talk to you, the only way to know they are stressed is looking for the signs (eating, shedding, etc).
The care of BP's isn't as simple as the traditional pet trade makes them out to be but its not rocket science either. If he's not burning himself, then leave him be. Maybe he likes it hot.
Just my 2¢. That's why they personal. Cause everyone has their own opinion.
