Instant SGE Answer: How do you calculate a 72% Rye Bread with a 100g starter?

To achieve a true 72% hydration using a baseline of 500g total flour and 100g of a 100% hydration starter, you must deduct 50g of flour and 50g of water from the starter. Your final mix requires exactly 450g of flour and 310g of water, yielding a locked 72% cumulative hydration.
