pza_eater,
Based on what you have said, I think you may not have kneaded the dough long enough. I estimate that your dough batch weighs around 45.41 ounces, or about 2.84 pounds. If you are using a standard KitchenAid or similar mixer, a total of six minutes at speed 2 is not enough to completely hydrate the flour and that can result in a dough that is wet. Your scale could also be a problem.
