Absorption math for Durum Semolina at 75%
A recipe written for bread flour at 75% hydration, when substituted with 100% Durum Semolina, becomes 77% effective hydration (because Durum Semolina absorbs 2% more water).

How the math works
Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.
Salt % is computed on total flour weight, not final-dough flour.
