AJ, there's an equalizing element to longer bakes. The lower temp balances out top and bottom heat as well as back and front heat and usually gives you an evenly colored pie without needing to either broil or turn the pizza mid bake. It's typically not the best pizza from an oven spring perspective, but, it's evenly colored. When you start using more conductive hearth materials and reducing your bake times, though, that all changes. No setting it and forgetting it.
In all fairness, if you walk into any NY mom & pop pizzeria, even the countless mediocre ones, the guy manning the oven isn't taking long breaks as the pizzas bake. He's launching, turning, checking the bottom, maybe turning one more time, then retrieving. Tending the oven is the nature of the NY style pizza beast. When I entertain, I'm not sitting around talking much. I might make 4 or so pies, then take a break and sit down and eat a slice or two, but, then it will be back to the oven. NY doesn't involve the amount of labor that you see in a wood fired oven Neapolitan bake, but it's still a considerable amount of time spent in front of the oven. You don't get truly great pizza and maximum time with your guests/family. You have to sacrifice for your art
You're a pizza guy now
If you really want to maximize your time with your guests, try bringing your guests to your kitchen/oven area and have them sit and eat (or even participate) while you're putting on your show.
So, yes, you have to broil, and you have to turn. You have to man the oven- for all 8 pies. You can, with some trial and error, dial in exactly when to turn the broiler on to get the perfect coloration on top when the bottom is done, but, for the first few times, it takes a lot of fidgeting.
You want the aluminum plate about 5-6" away from the broiler. This usually translates into the second shelf down. It really depends on the broiler, but if you're doing a 4 minute bake on the bottom (500-525 with 1/2" aluminum), I'd turn on the broiler after 1.5 minutes and then start checking (and turning) the top for color around 3.
