Can anybody give me an example of a course, classic or otherwise, that suffers from a manifestly incorrect course rating or slope? I can't say that I've ever heard this complaint, much less a problem with penalty strokes on ANY course.
Lots of complaints about hole handicapping (which most golfers don't understand AND which is done by the club rather than the golf association anyway) and about handicaps being either sandbagged or vanity. But the course rating?
