This article can be used to calculate how long it will take to repair a Generator 
under given circumstances.
Calculation[]
Important Notes[]
- Base Repair Efficiency Spreadsheet:
| Repairing Survivors | Individual Efficiency | Combined Efficiency | Time to repair a Generator |
|---|---|---|---|
| 1 Survivor | 1.0 c/s | 100 % | 1.0 c/s | 80 seconds |
| 2 Survivors | 0.85 c/s | 85 % | 1.7 c/s | ~47.06 seconds |
| 3 Survivors | 0.7 c/s | 70 % | 2.1 c/s | ~38.1 seconds |
| 4 Survivors | 0.55 c/s | 55 % | 2.2 c/s | ~36.36 seconds |
- Unlockables affect the Repair Efficiency, not the Repair Times directly.
Formula[]
Base Repair Time t in seconds =
t = (80 charges)/η
Repair Efficiency η in c/s (Individual) =
η = 1 – 0.15 × n
where
n = (Number of Survivors) - 1
Example[]
Two Survivors repairing a Generator simultaneously. The both have the Prove Thyself 
perk equipped.
Base Repair Efficiency (without Prove Thyself, Individual):
η = 1 – 0.15 × (2-1)
η = 1 – 0.15
η = 0.85 c/s
Repair Efficiency with Prove Thyself (Individual):
η = 0.85 + 0.85 × 0.15
η = 0.85 + 0.13
η = 0.98 c/s
- Each Survivor is performing the Repair Action at a speed of 0.98 charges per second, accounting for a 1.96 c/s (0.98 * 2) total Repair Speed.
