Cooking pizzas using two stones/steel vs one stone/steel in consumer oven So I use a regular oven to cook my pizzas, and I use a steel platform. 

It works great, and the pizza comes out amazing. The throughput is low, so I was wondering if it would be a good investment to get a second steel platform so I can cook two pizzas at a time. 

Would there be a huge difference in cooking two pizzas at a time vs one?
Would it take longer for the platforms to heat up than the hour I typically give it? 

I use an electric oven, and it seems to work fine at 500 degrees (or whatever its true maximum is)
Having 2 stones/steels in the oven is totally workable, the top one would cook a bit faster than the bottom one but that's not a dealbreaker. 2 steels will take longer to get up to temperature than one, whether an hour is enough in your oven is not something I could say. I would suggest you get an infrared thermometer so you can take measurements and know for sure, they are cheap and take the guesswork out of it.
