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 Pan de Cristal

Mix in stand mixer: all flour, 60% of water, oil, salt, levain. Gradually add remaining water over 5-10 min while mixing until dough is fully developed but extremely loose. 4 sets of coil folds every 30 min in first 2h, then rest for 2 more hours. Gently tip onto heavily oiled sheet pan. Cut into 4-6 rectangles with oiled bench scraper. Short 1h proof. Bake 500°F with steam, 18-22 min.

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.
