How the calculator uses this flour

Fermentation window. With 11.7% protein, the dough peaks after about 7 h at 22°C, inside a 3.5–11 h window. In the fridge at 4°C, it holds up to 24 h.
Hydration range. From its specs, Pandough estimates 58–70% water, and the calculator's hydration band starts there. For Traditional Napoletana in a 290°C home oven, it recommends 64–68%.

King Arthur Organic All-Purpose Flour fermentation range

The catalog window for King Arthur Organic All-Purpose Flour is 0–24 hours at 4°C (39°F). Pandough estimates yeast and timing from that window plus your hydration, salt, yeast type, and the temperatures the dough actually sees.

Fermentation time also depends on dough temperature, yeast amount, hydration, and the split between warm and cold proofing.
