I'm going to level with you. Over firing is my biggest fear being as inexperienced as I am. I bought an infared thermometer and obsessively check it lol! After a few fires I'm starting to get comfortable
I was more laughing about the "about 599 F". Yep, I can still remember the apprehension the first nights the fire was still going and I went to bed. Nothing wrong with being careful when playing with fire in your house.
