I believe that brad randall is correct on this one if we are talking about the dough formulation at the PMQ Recipe Bank–with 46 pounds of flour and 16 ounces of oil. The 46 pounds of flour equals 736 ounces (46 x 16 = 736). With 16 ounces of oil, the baker’s percent for the oil is 16/736 = 2.17391%, or roughly 2.2%, which is the baker’s percent figure given in the Big Dave Recipe Bank recipe.
As a practical matter, there shouldn’t be a big difference. 16 ounces of vegetable oil is equivalent to almost 100 teaspoons. 16 fluid ounces, or two cups, comes to 96 teaspoons. So, the difference is about 4 teaspoons.
