I an unaware of any flour that can yield total carbohydrates of 8 x 36 = 288 grams for the amount of flour that we are talking about in this thread.
Generally speaking, the higher the protein content the lower the carbohydrate value. For example, consider these carbohydrate values per 100 grams of flour:
All Trumps: 70.6 grams , or 195.96 grams total (for Pepe's 2.0) (14.2 +/- 0.3% protein)
KASL: 70.26 grams, or 194.99 grams total (14.2 +/- 0.2%)
KABF: 72.53 grams, or 201.32 grams total (12.7 +/- 0.2%)
Better for Bread: 73.10 grams, or 202.9 grams total (12.0 +/- 0.3%)
KAAP: 72.73 grams, or 201.88 grams total (11.8 +/- 0.2%)
Generic AP flour (10% protein): 76 grams, or 210.95 grams total (10%)
GM Cameo pastry flour: 77.3 grams, or 214.56 grams (9.0 +/- 0.9%)
GM Purasnow cake flour: 78.3 grams, or 217.34 grams, or 217.33 grams (8.2%)
There are a couple of flours that have higher than average carbohydrate values. Consider these two Pendleton flours:
Pendleton Power: 77.9 grams, or 216.23 grams total (13.0 +/- 0.3%)
Pendleton Mondako: 73.90 grams, or 205.12 grams total (12.0 +/- 0.3%)
As you can see from the above, none of those flours comes anywhere close to 288 grams. The yeast also contains some carbohydrates, but with the 7.63 grams of cake yeast in Pepe's 2.0, you can add 1.35 grams of carbohydrates to the above numbers.
I suppose that Pepe's may have had flours milled especially for them, but I am hard pressed to make out a case of any flour that can deliver the carbohydrate values in the Pepe's Nutrition Facts. Well, you might say that maybe Pepe's was using more flour. Using the BforB flour as an example, to get a total of 288 grams of carbohydrate, you would need (100 x 288)/73.1 = 393.98 grams of flour. That in 13.9 ounces. The whole dough ball weighs around a pound. That leaves 2.1 grams for the water, yeast and salt. It doesn't compute.
I also considered that maybe Pepe's added vital wheat gluten to its dough, which is commonly done for frozen dough balls. However, that only makes the carbohydrate values go down even more, for the reasons mentioned above.
