Developing an optimal scoring system with a special emphasis on volleyball

Scoring systems for two-team (two-person) net games are typically evaluated for accuracy, efficiency, and variability. This evaluation may be difficult if many points are involved, the probability of winning a point changes with service, and/or points are not scored every rally. A computer program that may be used to evaluate general scoring systems for accuracy, efficiency, variability, and expected score difference is presented. Four scoring systems, side-out, quick, side-out point, and bonus point, are analyzed. A list of items to consider when developing an optimal scoring system is suggested. An optimal scoring system for volleyball is introduced.
