As promised, I have presented below the ingredients, quantities and baker's percents (which are the same for all doughs) for the four different size pizzas--10" (9 oz. dough ball), 12" (12 oz.), 14" (18 oz.) and 16" (22 oz.). Please keep in mind that the kneading time will not be identical for all four sizes, so attention should be paid more to the condition of the dough ball rather than knead time per se. Also, for those who choose to use the volume measurements rather than using a scale to weigh ingredients, I suggest that you use the scoop and level technique for measuring the flour, that is, scoop the flour out of the bag and into the measuring cup until it is a bit overfull and then level off the top of the measuing cup until it is flush by using a flat edge, such as the flat edge of a knife. That is the technique I use to convert from weight to volume in recipes, so using the same technique should keep us pretty close together. When measuring water by volume, be sure to look at the level of the water on a flat surface at eye level. Even that isn't particularly accurate (because of the meniscus) but it is the best that the human eye can do.
For those who can handle baker's percents and wish to calculate dough ball weights for other size pizzas, I calculated the thickness factor TF to be around 0.11, which is typical of a medium thickness pizza. All that is necessary is to solve for W in W = 3.14 x R x R x 0.11, where R is the radius of the size of pizza to be made, and then use the baker's percents to calculate the amounts of all of the ingredients for the related dough ball.
Readers might also be interested to know that while the Old Faithful recipe instructions say to mix the oil in with the water, Big Dave himself has indicated on numerous occasions that it may be better to knead in the oil separately, a practice recommended by his colleague Tom Lehmann. Keep in mind also that bake times will have to be adjusted to accommodate each size of pizza.
Here are the four scaled-down recipes.
