Minor correction on my part: > For a period of a week, each day mix an equal amount of flour and water by weight. I always use 100g of water and 100g of flour.

Minor correction on my part: > For a period of a week, each day mix an equal amount of flour and water by weight. I always use 100g of water and 100g of flour. This is considered 50% hydration. I meant to say this is 100% hydration (when water and flour are equal parts).
