Abstract
A method and apparatus for determining an angle of attack of a golf swing based on multiple ball hitting is disclosed. Multiple golf balls of different known constructions are hit by a golfer. Club head speed and backspin data associated with each of the hit golf balls is measured. Based on a correlation between an angle of attack and measured data associated with the golf balls of different known constructions, an angle of attack of a golf swing can be determined. Different sets of golf balls of known constructions can be provided based on characteristics of a golfer. A kit including at least three golf balls of different known constructions and a database containing the correlation between data associated with the at least three golf balls and an angle of attack is also disclosed.
