Why the timing shifts
Hot kitchen — summer without AC, near-window light. Ferment nearly 2× faster than baseline. Not ideal — fermentation outpaces gluten development, leading to over-acidic flavor and collapsed structure. If unavoidable, use very low levain (10-12%), minimal bulk (2h max), and get dough into cold retard ASAP. Consider reducing bulk temperature by moving dough to cooler location (basement, refrigerator brief intervals).
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.
