Method of evaluating a golf club
First Claim
1. A method of evaluating a golf club comprising the steps of:
- a step (St1) of using at least one computer for determining motions of the golf club during a swinging motion of a golf player including a period ranging from a time (Ts) to a time (Tf);
a step (St2) of using the at least one computer for obtaining power index values (Pw) in a time series during the period ranging from the time (Ts) to the time (Tf), based on the result of the determination;
a step (St3) of using the at least one computer for obtaining a power integration value (Sp) by integrating the power index values (Pw) during the period ranging from the time (Ts) to the time (Tf);
a step (St4) of using the at least one computer for calculating club energy (Eg) of the golf club at the time (Tf); and
a step (St5) of using the at least one computer for quantitatively evaluating club suitability based on the power integration value (Sp) and the club energy (Eg);
wherein each of the power index values (Pw) is a value which is correlated to power of a work provided from the golf player to the golf club; and
wherein the club suitability is evaluated based on a ratio (Sp/Eg) of the power integration value (Sp) relative to the club energy (Eg).

Abstract
A method of evaluating a golf club is disclosed. The method includes a step (St1) of determining motions of the golf club during a swinging motion of a golf player including a period ranging from a time (Ts) to a time (Tf); a step (St2) of obtaining in a time series power index values (Pw) during the period ranging from the time (Ts) to the time (Tf), based on the result of the determination; a step (St3) of obtaining a power integration value (Sp) by integrating the power index values (Pw) during the period ranging from the time (Ts) to the time (Tf); a step (St4) of calculating club energy (Eg) of the golf club at the time (Tf); and a step (St5) of quantitatively evaluating club suitability based on the power integration value (Sp) and the club energy (Eg). Each of the power index values (Pw) is a value which is correlated to a power of a work provided from the golf player to the golf club.
