## How Proofing Time Is Estimated
### Factors Affecting Proofing
- **Temperature**: Yeast is most active at 75-80°F. Lower temperatures slow fermentation; higher temperatures speed it up.
- **Yeast amount**: More yeast means faster rising. The standard is 2.25 tsp (one packet) per 3 cups flour.
- **Flour amount**: More flour takes longer to rise because there is more structure to inflate.
### Formula
**Proofing Time = Base Time x (75 / Room Temp) x (2.25 / Yeast) x (Flour / 3)**
Base time is approximately 90 minutes for a standard dough at 75°F. The second rise is typically 60% of the first rise time.

Exemple Résolu
Estimate proofing time for a standard dough (3 cups flour, 2.25 tsp yeast) at 72°F.
- Temp factor = 75 / 72 = 1.042.
- Yeast factor = 2.25 / 2.25 = 1.
- First rise = 90 * 1.042 * 1 * 1 = 94 minutes.
- Second rise = 94 * 0.6 = 56 minutes.
- Cold proof = 94 * 0.15 = 14.1 hours.
