*When mixing dough (pizza, bread, or bagels), check your "AR" absorption ratio - water weight divided
by flour weight. The above capacities are based on 12% flour moisture at 70°F water temperature.
If high gluten flour is used, reduce above dough batch size by 10%.
Example: If recipe calls for 6 lb. of water and 10 lb. of flour, then 6 divided by 10 = 0.6 (60% AR).
