Why the timing shifts

BASELINE — the reference temperature for all fermentation times in this system. Warm kitchen, proofing box, summer AC setting. 76°F (24.4°C) is the classical bakery target. If you control dough temperature via dough desired temperature (DDT) calculations, aim for this range. All published recipe times assume this temperature unless otherwise noted.

Technique for Focaccia

Mix everything at once (no autolyse). 3-4 stretch-and-folds. 3h bulk at 76°F. Heavily oil a quarter-sheet pan (at least 3 tbsp olive oil). Transfer dough, gently stretch to fill pan. Proof 90 min. Dimple with oiled fingertips to create deep wells. Drizzle olive oil over, sprinkle flaky salt. Bake at 450°F for 22-25 min until golden brown on top and bottom.

How the math works

Multipliers are piecewise-linear interpolations between reference points measured by Myhrvold et al. in Modernist Bread vol 3. 76°F is the baseline (1.0×); every 10°F drop roughly doubles fermentation time, and every 10°F rise roughly halves it.
