Yes humidity and ambient improved slightly. My temp thermometer is approx. 6 inches from the top of the cage and humidity gauge is close to the center. Average 75-82F ambient and 30-60% humidity. But this varies based on your house conditions. What works for me may not work for you.
I'd start with the sides and see what happens. If you need more, do the back, then do the front door if needed. I'd leave the bottom door open to allow air flow.
