## How Point Differential Is Calculated
### Formula
**Point Differential = Points Scored - Points Allowed**
**Per-Game Differential = Total Differential / Games Played**
### Why It Matters
Point differential is one of the best predictors of future team performance. Teams with large positive differentials tend to sustain success, while teams with negative differentials despite winning records often regress.

计算示例
420 points scored and 380 allowed in 16 NFL games.
- Total differential = 420 - 380 = +40
- Per game = 40 / 16 = +2.5 points per game
- PPG scored = 420 / 16 = 26.3
- PPG allowed = 380 / 16 = 23.8
