Although I have been lurking here for a year, this is my first post. Let me start out by saying how terrific this site is and how much I have learned. Thanks so much (and I bought Floyd's book - terrific!).
I have been baking sourdough breads, with my own starter, for about a year. My usual process, from Emmanuel Hadjiandreou "How to Bake Bread" (wonderful, btw) is to stretch and fold every 10 minutes for about an hour, ferment for an hour, shape, proof for 4 hours, then bake.
