Columbia Business School

NEW YORK - What does it take to drop ten strokes from your golf score? What is the secret behind Tiger Woods's game? The surprising answers can be found in Every Shot Counts: Using the Revolutionary Strokes Gained Approach to Improve Your Golf Performance and Strategy. The new book from Columbia Business School Professor Mark Broadie expands upon the strokes gained putting stat he developed and which is now in use by the PGA Tour.

"Many golfers are focusing on the wrong stats when evaluating their game. Traditional golf stats such as putts per round, fairway hit, and greens in regulation actually provide little insight into golf performance," says Broadie. "By using a statistical approach to analyze millions of shots, Every Shot Counts shows golfers of any skill level how to make better strategic decisions on the course."

The strokes gained method makes it possible to analyze a player's entire game by calculating the advantage gained or lost for every shot, compared to a consistent standard. The method is based on data collected by the PGA Tour on every shot by every player at its tournaments since 2003. Amateur golf data has been collected since 2005 using a computer program Broadie developed called Golfmetrics.

Broadie uses the approach to answer many questions about golf performance including:

  • How much is twenty extra yards of driving distance actually worth?

  • What are the most important skills separating amateurs from pros?

  • How does one best understand strengths and pinpoint weaknesses?

Every Shot Counts is not a book about golf mechanics. Instead, using statistical data from the past decade, it is designed to show golfers of all handicaps new ways to improve golf strategy and measure performance.
