A variation on SJSD and other bakes

I meant to start this batch early yesterday, but welcomed an old friend from out of town in the morning, pushing bake my mixing schedule back. It was HOT here yesterday with the mercury touching 32C outside and my kitchen 24 - 25C. I am following David Snyder's San Joaquin Sourdough formula, but with the elevated temperatures, reduced time between folds to 20 minutes for the first 4 and down to 30 minutes in the bulk stage. After the first 30 minutes the dough had risen by nearly a half.
