I recently redid my spreadsheets to match current practice. First is "worksheet", second goes on wall while I work. It doesn't really matter if you're consistent and don't care about comparing notes with others, but I account for board flour, shrinkage, to nail actual hydration as if this were a chemistry lab experiment. I've seen other accomplished bakers who ignore the starter hydration, for example. Their effective hydration is a local fantasy.
We grind some of our flour. We've been buying white from Acme Bread, famed in Bay area. They have Guisto's make this for them, but likely a different blend than one can buy elsewhere.
I learned to accelerate the hydrolyse for each step by 60 seconds in a vacuum sealer chamber. This makes an obvious difference for pasta dough, and I believe a difference here too.
I rediscovered "bassinage" where one kneads the dough at a comfortable hydration, then adds water at the end using Chad Robertson bowl folds. I like to knead a long rope, fold it over and twist, knead again to a long rope... My theory here is that one does better with a kneading technique that doesn't cause the bran to cut through the developing gluten.
We use the KK in summer to avoid heating the house, and a convection oven in winter.
I used to worry about filling the oven with ample steam. We now swear by the Challenger Bread Pan.
