BUT, if it is found to significantly improve scores it is banned. The object is to keep the scoring on given holes the same regardless of technology. Certain golf ball innovations have been genuine improvements, and have been in due course banned. Similarly the between the legs symmetrical swinging putter, favoured by one top professional at one stage, was found to convey a genuine advantage and was also banned. Some will want to stop about here :-): A similar effect occurs in modern (and also not so modern) science, except, if you can manage an end run around the rules system and achieve a bull run you win and get to propose the next set of rules. These may then, in turn, be bent as much as possible and quite a bit more to try to stop the next challengers gazumping you. Even when faced with manifest defeat of the old rule system skilful protagonists can sometimes hold out for decades by subtly accommodating the new as a temporary aberration which will pass in a decade or two. By the time the emperor is found to truly have no clothes the old guard are mostly dead and beyond caring.
