- Worth noticing
- Its worked example counts a 100%-hydration starter as 50 g flour and 50 g water before scaling.
Field notes
The example begins with 500 g of flour and 325 g of water added outside the starter, then counts the starter’s contributions separately. At a 1,000 g total-flour target, the page shows a 1.8182 scaling factor and approximate ingredient masses. Its stated model is deliberately limited: other wet ingredients are not treated as pure water, and flour type or mixing can affect dough feel.
