Why the timing shifts

Refrigerator territory — used for overnight retard during proofing or bulk slowdown. 12-16 hours at this temperature is equivalent to 1-1.5 hours at 76°F baseline. Essential for flavor development in artisan sourdough. Cold retard improves shape retention, enables flexible scheduling, and develops deeper tangy flavors. Place dough in floured banneton, cover, refrigerate at this temperature.

Technique for Sourdough Naan

Mix dough with yogurt + water. 3h bulk. Divide into 100g pieces, short 1h proof. Stretch into teardrop shape. Cook on very hot cast-iron skillet (or under hot broiler) 90 sec per side. Brush with melted butter/ghee, optionally sprinkle fresh herbs (cilantro).

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.
