I  had always known that there was no standardization in shaft stiffnesses from one manufacturer to another but felt that within the specific  companies there would be a standard for these designations. In my recent  work with The Ben Hogan Golf Co. to set up their Club fitting system  using a wide variety of shafts, I even found this to be wrong. The  following table summarizes the difference in the natural frequency of the various designations in the products of several Manufacturers.

▪ Natural Frequency Deviation in     Cycles/Minute - cpm by Manufacturer for X, S and R shafts


                            Shaft Stiffness       X     S     R
                            Manufacturer1      51   50   41
                            Manufacturer2      10   63   80
                                       Manufacturer3        6   23    24
                            Manufacturer4      23   17    23
                            Manufacturer5             13   22
                            Manufacturer6            20   19
                            Manufacturer7      24   14     8
                                      Variance  Low to 

                           High in group of 7  51   63   80

Understand  that if you are told you need an X stiff shaft for your swing, to get the right one from this group of manufactures, you are searching in an  low to high range of 51 cpm. What does this mean? To get a fit that will  give you your best distance and accuracy we have found you must be  within 4 cpm of the correct natural frequency to fit your swing timing.  It is up to the fitter to pick that shaft for you but he must know your  natural frequency requirement and the frequency of the selected shaft  when built into the club assembly. Trying to get the correct frequency  by just knowing you need an R, S or X is hit and miss. We can see why it  is mostly miss if you do not know the exact frequency you need and the  frequencies of the club when built with the selected shaft. Using frequency as the designation is the most accurate way of designating  club stiffness and does not change from manufacturer to manufacturer.  This is the basis of the fitting system that has been developed by Perfected Golf Group, Ltd. .
