And you were using the bake/lower heating coil setting and not the
broil/upper coil right? Then the pizza stone will block the radiant
heat from the coil and slow things down. (there are of course some
"it depends" factors)

I've noticed with many gas ovens, when on bake, most of the hot gases
come up around the sides and back edge. In this situation, a stone
or pan, lower down and in the middle won't matter as much.

Flip side is a pan or other cooking container is close to the sides or
back, it will get a hot spot/edge there.
