Why the timing shifts
Very hot — avoid. Mold risk rises sharply above 85°F. Fermentation outpaces structural development. Levain becomes unbalanced toward lactic acid producers, creating cloying sour flavor. Only use briefly for refreshing starters or if absolutely unavoidable. Move dough to cooler location, or skip this bake and wait for cooler conditions. If baking must happen, reduce levain to 8%, bulk 90 min max, get into refrigerator immediately after shaping.
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.
