Accurate club fitting primarily uses what type of data?

Accurate club fitting relies heavily on physical measurements of the golfer. This is crucial because these measurements help determine the appropriate specifications of the clubs, such as length, lie angle, and swing weight, which directly influence how the club interacts with the ball during play.

Physical measurements can include a golfer’s height, arm length, wrist-to-floor measurement, and grip size. By gathering this data, a fitter can tailor the clubs to match the golfer's unique physical attributes and swing characteristics, leading to improved performance and comfort.

While a golfer's personal preferences are also important in the fitting process, they are secondary to the objective data provided by physical measurements. Scorecard statistics can inform the fitting indirectly by highlighting areas of improvement, but they do not provide the specific, actionable data needed for precise club adjustments. Weather conditions can impact performance on the day but do not play a role in the fitting process itself. Therefore, physical measurements are foundational for achieving an effective club fitting.
