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 Sourdough Tortilla
Mix all ingredients (fat cut in like pie dough). 30 min rest only. Divide into 60g balls, roll thin (about 7 inches). Cook on dry cast-iron skillet at medium-high heat (400°F) for 30-45 sec per side until lightly browned with some bubbles.

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.
