How the calculator uses this mixer

Water temperature. Pandough uses the typical friction factor for its type, 11. To reach 24°C dough in a 22°C kitchen, the calculator asks for water at 17°C, against 25°C when mixing by hand.
Batch size check. At 60% hydration, the calculator flags batches over 17 kg. For a 50% biga, the limit drops to 7 kg. Under 1.8 kg, it warns that the batch is too small.

Formulas this mixer handles

The largest single batch for each formula at its own hydration. The limit is the same one the calculator checks your batch against.
