The United States Golf Association tests golf balls to ensure that they conform to the
rules of golf. Balls are tested for weight, diameter, roundness, and overall distance. The
overall distance test is conducted by hitting balls with a driver swung by a mechanical
device nicknamed "Iron Byron" after the legendary great Byron Nelson, whose swing the
machine is said to emulate. Following are 100 distances (in yards) achieved by a
particular brand of golf ball in the overall distance test.
