Gary Mayes began testing golf balls in 1999 to understand and quantify their differences. His research led to the granting of U.S. Patent 7,918,751, Method of Rating Golf Balls. The patent provides a testing and rating method to obtain performance data on golf balls in a manner that will assist golfers in selecting a golf ball that meets their specific swing profile, equipment, feel and price criteria. In 2006, Mayes co-founded GBT Technologies, LLC where he was a Partner serving as the Chief Technologist. GBT developed the original GolfBallSelector.com and GolfBallTest.org sites and a second patent, U.S. Patent 9,914,038 Systems and Methods for Golf Ball Selection was issued as a result of this work.
