I agree with you that you’re going to have to change the way you make your dough. The old guess and by gosh method of portioning the dough ingredients just doesn’t cut it with consistency.
I highly recommend that you begin establishing the weight of each ingredient used and begin weighing them.
I see that you don’t have any salt in your dough formula. This can/does have a great influence on the flavor of the finished crust, making it rather bland and starchy tasting.
As for your oven finger profile, typically, all of the bottom fingers are open, and when radiant panels are used on the top, only some (one or two) are radiant, the rest are impingement panels of some form. Also, the bake temperature is WAY TOO HOT at 275C/527F. I can see why your cheese is burning.
As for your pans, it sounds like you are using a brightsilver colored pan, possibly the worst choice. These pans are intended to be seasoned, which gives then a golden color initially, which turns to a dark brown/black with continued use. The black anodized pans are actually a much better choice as you don’t need to worry about the seasoning coming off if the pans are soaked in hot soapy water for cleaning. The reason for the dark colored pans is because the dark color absorbs the heat, making for a much better bottom bake, at a lower, more efficient baking temperature, where as the bright colored pans reflect the heat away, making it more difficult to bake the bottom of the pizzas (physics 101).
My suggestion is to find out exactly what you have for a top finger profile (all, 100% radiant panels??) I truly think this is wrong, and that something along these lines would be better suited: closed - open- open- closed. The last top finger may need to be adjusted to control the top bake and the cheese color. The baking temperature should be in the 450 to 475F/232 to 246C range, and the baking time should be in the 6 to 8-minute range, or slightly longer depending upon which oven you have. The pans should be black anodized or well seasoned. For flavor and improved dough performance, you should be adding salt to the dough formula. We typically add 1.75% salt based on the weight of the flour. You can make a lot better product, with the characteristics that you are looking for, but you’re going to have to make some changes.
Please keep me posted on your progress.
