## Volleyball Attack Efficiency
Attack efficiency is the single most important hitting statistic in volleyball, balancing kills against errors and total swings.
### Formula
**Efficiency = (Kills - Errors) / Total Attempts**
The result ranges from -1.000 (all errors) to 1.000 (all kills). Zero means kills equal errors. In college and professional volleyball, an efficiency above .300 is excellent and above .400 is elite.

计算示例
A hitter records 15 kills, 4 errors, on 35 attempts.
- Efficiency = (15 - 4) / 35 = 11 / 35 = 0.314
- Kill percentage = 15 / 35 x 100 = 42.9%
- Error percentage = 4 / 35 x 100 = 11.4%
