That makes a lot of sense. I think one could perfect the use of the oven with some simple testing. For example, setup a timer for each oven whereby an oven that is preheated but the propane or gas is turned down to low can be instantly heated (1 to 2 minutes), a pizza is thrown in there for 3 to 4 minutes, pizza is removed, and oven gas is reduced to minimum and allowed to cool for 2 to 3 minutes before process is restarted. In this manner, one pizza can be cooked every ten minutes but each pizza will be served within 5 minutes. Add in the fact that there will be 4 or 5 of these ovens and it is feasible to pump out up to 5 pizzas every 10 minutes and around 100 pizzas an hour.
Of course, this would require much precision in the way the ovens are operated. However, I see no reason why I could not automate this process by computer interaction with the gas lines and display readouts at each oven.
Just a thought.
