Terry,
The preferment dough calculating tool does not work using the preferment as a standalone ingredient as you used it, so I had to get a hand calculator and pencil and paper out and rearrange things so that I could then use the preferment dough calculating tool. If I got the math right using the data you provided, this is what I got for a single 22.5-ounce dough ball for an 18" pizza:
Total Formula: Flour (100%): Water (66.5072%): Salt (3%): IDY (0.15%): Total (169.6572%):
Preferment: Flour: Water: Total:
Final Dough: Flour: Water: Salt: IDY: Preferment: Total:

For a dough batch for twenty 18" pizzas, or a total dough batch weight of 450 ounces, the dough formulation would look like this:
Total Formula: Flour (100%): Water (66.5072%): Salt (3%): IDY (0.15%): Total (169.6572%):
Preferment: Flour: Water: Total:
Final Dough: Flour: Water: Salt: IDY: Preferment: Total:
| 7519.57 g | 265.24 oz | 16.58 lbs 5001.06 g | 176.4 oz | 11.03 lbs 225.59 g | 7.96 oz | 0.5 lbs | 15.67 tbsp | 0.98 cups 11.28 g | 0.4 oz | 0.02 lbs | 3.74 tsp | 1.25 tbsp 12757.5 g | 450 oz | 28.12 lbs | TF = N/A 338.38 g | 11.94 oz | 0.75 lbs 338.38 g | 11.94 oz | 0.75 lbs 676.76 g | 23.87 oz | 1.49 lbs
7181.19 g | 253.3 oz | 15.83 lbs 4662.68 g | 164.47 oz | 10.28 lbs 225.59 g | 7.96 oz | 0.5 lbs | 15.67 tbsp | 0.98 cups 11.28 g | 0.4 oz | 0.02 lbs | 3.74 tsp | 1.25 tbsp 676.76 g | 23.87 oz | 1.49 lbs 12757.5 g | 450 oz | 28.12 lbs | TF = N/A

As you can see, using the 50/50 starter as you did results in a total formula hydration of 66.5072% rather than 65%. Also, the other numbers, for example, for the starter, salt and IDY, change slightly when using the preferment dough calculating tool. Of course, you can reorder the ingredients like you did, but then you would have to use a hand calculator and pencil and paper (or create a spreadsheet) if you want to change dough batch sizes. With the preferment dough calculating tool, if you use the 66.5072% hydration figure, the tool will do the recalculations for other dough batch sizes. I did not include any bowl residue compensation in the above dough formulations. If you decide to drop the IDY altogether, that will change the numbers a bit if you want to maintain the 22.5-oz. dough ball size. In that case, the dough formulation would look like this for 20 dough balls:
Total Formula: Flour (100%): Water (66.5072%): Salt (3%): Total (169.5072%):
Preferment: Flour: Water: Total:
Final Dough: Flour: Water: Salt: Preferment: Total:
| 7526.23 g | 265.48 oz | 16.59 lbs 5005.48 g | 176.56 oz | 11.04 lbs 225.79 g | 7.96 oz | 0.5 lbs | 15.68 tbsp | 0.98 cups 12757.5 g | 450 oz | 28.13 lbs | TF = N/A 338.68 g | 11.95 oz | 0.75 lbs 338.68 g | 11.95 oz | 0.75 lbs 677.36 g | 23.89 oz | 1.49 lbs
7187.55 g | 253.53 oz | 15.85 lbs 4666.8 g | 164.61 oz | 10.29 lbs 225.79 g | 7.96 oz | 0.5 lbs | 15.68 tbsp | 0.98 cups 677.36 g | 23.89 oz | 1.49 lbs 12757.5 g | 450 oz | 28.13 lbs | TF = N/A

For your purposes, when I used your baker's percents for a single dough ball, I got the following after using the total percents figure (177.15%) to calculate the amount of flour (12.7011 oz.) for a single 22.5 oz. dough ball:
100%, Flour, 12.7011 oz.
65%, Water, 8.255715 oz.
9%, Starter, 1.143099 oz.
3%, Salt (Morton's Kosher), 0.381033 oz.
0.15%, IDY, 0.0190516 oz.
Total percents = 177.15%
Total weight = 22.5 oz.
