Why the timing shifts
Warm kitchen or proofing box — ideal for accelerating fermentation. Ferment 25% faster than baseline. Good for schedule compression. Watch carefully — dough over-proofs quickly. Ideal for hot-weather baking when you want to get dough into cold retard before too much fermentation happens. Consider reducing levain to 12-15% to slow things back down.
Technique for Focaccia
Mix everything at once (no autolyse). 3-4 stretch-and-folds. 3h bulk at 76°F. Heavily oil a quarter-sheet pan (at least 3 tbsp olive oil). Transfer dough, gently stretch to fill pan. Proof 90 min. Dimple with oiled fingertips to create deep wells. Drizzle olive oil over, sprinkle flaky salt. Bake at 450°F for 22-25 min until golden brown on top and bottom.

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.
