Does it do this for any pizzas? or plain cheese pizzas? We have found that we need to push cheese only pizzas into the oven (about half to 3/4 of the pan started in the oven) or they get too dark.
You don’t really want to be too much about 500 degrees. However, I also agree about shooting for a time (we like around 7-7:20) and finding a temp to match it.
Also, the types of pan / screen makes a difference. We do not use screens (except for thin crust dough we buy) we use a round deep pan for pizzas and calzones.
