1. A method of mapping a plurality of performance variables of a face of a golf club head comprising the steps of:

  • A) identifying a face center on the face of the golf club head and storing the coordinates of the face center in a computer system;

    B) identifying a curvature profile of at least a portion of the face of the golf club head and storing the curvature profile in the computer system;

    C) computing a 3-dimensional face coordinate grid including at least a first face point located on a face toe portion of the golf club head, and a second face point located on a face heel portion of the golf club head, and storing the coordinates of the first face point and the second face point in the computer system;

    D) relatively positioning the golf club head and a measurement instrument via a positioning system controlled by the computer system to align a measurement instrument with the coordinates of the face center, wherein the computer system utilizes the face curvature profile so that the relative positioning ensures the measurement instrument alignment is approximately perpendicular to the face center;

    E) releasing the measurement instrument via the computer system to cause the measurement instrument to impact the face and determine a center face CT and storing the center face CT in the computer system;

    F) relatively positioning the golf club head and the measurement instrument via the positioning system controlled by the computer system to align the measurement instrument with the coordinates of the first face point, wherein the computer system utilizes the face curvature profile so that the relative positioning ensures the measurement instrument alignment is approximately perpendicular to the first face point;

    G) releasing the measurement instrument via the computer system to cause the measurement instrument to impact the face and determine a first CT and storing the first CT in the computer system;

    H) relatively positioning the golf club head and the measurement instrument via the positioning system controlled by the computer system to align the measurement instrument with the coordinates of the second face point, wherein the computer system utilizes the face curvature profile so that the relative positioning ensures the measurement instrument alignment is approximately perpendicular to the second face point; and

    I) releasing the measurement instrument via the computer system to cause the measurement instrument to impact the face and determine a second CT and storing the second CT in the computer system.
