In fact in the 'leadup' to WHS all Course Ratings in England (for men) were done using the USGA rating system as opposed to the EGU SSS system. The resultant CR was simply rounded and called the SSS. The Bogey Rating (and Slope) were simply stored 'til WHS came in.SSS is comparable to Course Rating.
Everywhere else in CONGU had been doing it for years.
