Jeff can check my work on this, but it he used a thickness factor of 0.14 and a bowl residue compensation of 1.5%, to make enough dough for two 9" x 9" pans, using the expanded dough calculating tool at
http://www.pizzamaking.com/expanded_calculator.html, I get the following:
Flour (100%): Water (75%): IDY (1%): Morton's Kosher Salt (2.5%): Olive Oil (5%): Total (183.5%): Single Ball:
 355.65 g  12.55 oz  0.78 lbs 266.74 g  9.41 oz  0.59 lbs 3.56 g  0.13 oz  0.01 lbs  1.18 tsp  0.39 tbsp 8.89 g  0.31 oz  0.02 lbs  1.85 tsp  0.62 tbsp 17.78 g  0.63 oz  0.04 lbs  3.95 tsp  1.32 tbsp 652.62 g  23.02 oz  1.44 lbs  TF = 0.1421 326.31 g  11.51 oz  0.72 lbs

Note: Nominal thickness factor = 0.14; for two dough balls for two 9"x 9" pans; bowl residue compensation = 1.5%
If the above is correct, if Josh wants to scale the above dough formulation for two pans, one 9" x 9" and the other 9" x 13", then the dough formulation for that case is:
Flour (100%): Water (75%): IDY (1%): Morton's Kosher Salt (2.5%): Olive Oil (5%): Total (183.5%):
 434.69 g  15.33 oz  0.96 lbs 326.01 g  11.5 oz  0.72 lbs 4.35 g  0.15 oz  0.01 lbs  1.44 tsp  0.48 tbsp 10.87 g  0.38 oz  0.02 lbs  2.26 tsp  0.75 tbsp 21.73 g  0.77 oz  0.05 lbs  4.83 tsp  1.61 tbsp 797.65 g  28.14 oz  1.76 lbs  TF = 0.1421

Note: Nominal thickness factor = 0.14; for dough for a 9" x 9" pan and a 9" x 13" pan; bowl residue compensation = 1.5%
Of the total dough batch weight, 326.31 grams (81/198 x 797.65 grams) will be for the 9" x 9" pan, and 471.34 grams (117/198 x 797.65 grams) will be for the 9" x 13" pan.
If Josh has already made a preferment with 1000 grams of flour and 750 grams of water, the total dough formulation looks like this:
Flour (100%): Water (75%): IDY (1%): Morton's Kosher Salt (2.5%): Olive Oil (5%): Total (183.5%):
 1000 g  35.27 oz  2.2 lbs 750 g  26.46 oz  1.65 lbs 10 g  0.35 oz  0.02 lbs  3.32 tsp  1.11 tbsp 25 g  0.88 oz  0.06 lbs  5.21 tsp  1.74 tbsp 50 g  1.76 oz  0.11 lbs  11.11 tsp  3.7 tbsp 1835 g  64.73 oz  4.05 lbs  TF = N/A

Note: No bowl residue compensation
If the last table is correct, Josh will have too much preferment and will have to scale it back to fit his pan situation (the second table above) or make more than two pizzas.
