The strokes gained concept was initially developed by Professor Mark Broadie of Columbia University, utilizing ShotLink data that has been made available to academic institutions for research since 2007. Strokes gained is a better method for measuring performance because it compares a player's performance to the rest of the field and because it can isolate individual aspects of the game. Traditional golf statistics, such as greens in regulation and putts per green, are influenced by a player's performance on shots other than those being measured.
