A better system for determining and monitoring a player’s level of ability is the Billiard University (BU) rating system. It assesses a wide range of important pool skills in a methodical, thorough, and consistent way. It also provides a numeric and descriptive rating. The BU rating comparison chart shows how the BU rating correlates to other commonly used rating and handicapping systems.
