Sounds like it’s spot on to me! As the weather changes, it may need adjustment, but it sounds perfect for now. I’ve had issues the past week with the freeze we had in my area. I just can’t get his basking spot high enough. It’s close, but not perfect right now.
It’s a learning curve for sure. This is my first Cham too and I stress all the time

I’ve never had any kind of reptile. So going from caring for warm blooded animals to a cold blooded one is night and day. The biggest thing I had to get used to was not feeding him every day. I have to remind myself that he isn’t like a dog or a bird or anything else. Even though it seems like it’s too hot at 80, or 3 bugs every other day isn’t enough, it’s what he needs.
