But if you take this argument to it’s logical conclusion then you wouldn’t have any anti cheating measures at all. Why bother with pre registering a GP score? Why bother insisting on a marker for a GP score? If the system is going to have some measures then it’s perfectly legitimate to comment on whether there should be more (or less).
I dont think either assumption there are correct. Pre registering, and a marker, are not there to prevent cheating, but only to be consistent with the conditions of a competition round, which by the rules of golf requires entry and a signed card. The WHS, and UHS as well, are fairly dispassionate mathematical attempts to rate each golfers play, on the evidence of past scores, to equalise all golfers. And both are imperfect at that which is difficult enough. And correctly, they avoid straying into the sphere of honesty policing.
