If not cooking at two different temperatures, what's best?
If I am not cooking at two different temperatures, is it best to take out the divider and use the whole oven instead of using just one section? Or is it OK to normally use only one section? Also, if I do take out the divider to use the whole oven, does it matter which set of controls I use - upper or lower? Or do I need to set both upper and lower to the same settings?
