You didn't indicate what size pizzas you made, but I estimate that the recipe you followed makes around 38.5 ounces of dough. That is for two pizzas, not three. So, it is possible that you changed the character of the pizza, and especially the crust, by not following Randy's instructions explicitly. If I were to use Randy's recipe, I would make two 14" pizzas. To make three pizzas, whether 12" or 14", would require scaling Randy's recipe to produce those results.
