Alternate characterizations of golf ball striking ability is provided, as well as methods for determining the alternate characterizations and systems for carrying out such determinations. Such methods may include performing one or more golf strikes to impart trajectories to one or more golf balls. Such methods may also include measuring each of the golf strikes to determine golf club head, golf ball speed, side spin angle, and offline angle, calculating a trajectory magnitude factor and a trajectory offline factor on the basis of the measurements, and reducing the trajectory magnitude factor by the trajectory offline factor.
A method for selecting a piece of golf equipment, the method comprising steps of:
A method of characterizing a golf ball striking ability, the method including steps of
A method of characterizing a golf ball striking ability, the method including steps of
A golf ball striking ability characterization for use in a golf ball fitting system, the golf ball striking ability characterization comprising at least a trajectory magnitude factor reduced by a trajectory offline factor, the trajectory magnitude factor including a ratio of a speed of a golf club head to a speed of a golf ball, and the trajectory offline factor including a sum of (a) the side spin angle of the golf ball modified by a side spin scaling factor and (b) a trigonometric function of an offline angle of a trajectory of the golf ball, wherein the speed of the golf club head, the speed of the golf ball, the side spin angle of the golf ball, and the offline angle of the trajectory of the golf ball are determined from measurements taken upon a plurality of golf strikes in which the golf club strikes the golf ball.
A system for evaluating golf ball striking ability for a computer comprising:
