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 15 kg. For a 50% biga, the limit drops to 10.5 kg. Under 1 kg, it warns that the batch is too small.
