The biscuits at the top photo baked in the top oven. The biscuits in the bottom picture baked in the bottom oven. The bottom biscuits were lighter than the top, especially the biscuits that baked in the front corners.
I baked these biscuits in the top oven with the convection fan turned on. The sheet of biscuits that baked on a higher rack (top left picture) were lighter than the biscuits that baked below them (bottom left). The pictures on the right are color representations of the brownness of the biscuits.

I broiled these hamburger patties in the top oven. These are the average times it took each burger to reach an internal temperature of 145 degrees Fahrenheit. The burger that cooked in the back-right corner cooked the fastest.
