A golf club swing speed chart measures a golfer's average swing speed as well as his highest and lowest swing speeds over the course of one or more games. Individuals can use these charts to compare player performances or to measure their own golf performances.
With enough information, individuals or organizations can create multiple golf club swing speed charts to measure different groups of golfers. This allows comparison of groups by performance, such as comparing the highest and lowest swing speeds, as well as comparing different groups, such as PGA and LPGA golfers. Using such charts over a period of years also measures changes in the participating players as time goes on.
