I moved the rack up a few notches so that the pizza would be closer to the broiling (top) heating element.
I did not use a stone on top in this test. Maybe next time. I wanted to use the broiling element to provide direct, intense, heat radiation.
When I put the pizza in the oven, after the preheat, I set the dial to broil.
I don't have a pizza stone, but using two layers of tile makes for more thermal mass (most pizza stones are not very thick).
