Abstract:
1. A computer-implemented method for corresponding a shaft with a specification code, the method comprising: receiving electronic data representing a measurement of shaft stiffness at each of at least three locations along the shaft; normalizing each measurement of shaft stiffness into an unitless integer relative to a corresponding one of a plurality of predetermined stiffness scales, a magnitude of increase between consecutive integer increments of the corresponding predetermined stiffness scale for one of the at least three locations being different than a magnitude of increase between consecutive integer increments of the corresponding predetermined stiffness scale for another of the at least three locations; and ordering the normalized integers into a set such that the first normalized integer represents the measurement of the shaft stiffness at a location closest to the butt end of the shaft and each subsequent normalized integer represents the measurement of the shaft stiffness at locations increasingly further away from the butt end of the shaft.
