It stays hot for quite a while. I put in 4 logs at the beginning, and no more after that. 2-3 hours after the temp peaks at 1000 deg + it will still be at 500+. I made a little door today for it and it stayed much hotter, longer. Cooked one pizza at around 1000, then waited and hour and cooked the 2nd pizza with the oven around 750-800. attached a few pics.
This pizza is just marinara, garlic, Pecorino Romano cheese, and olive oil.
