If short tricky courses are easy for scratch players but difficult for bogey players, then they should have high slope ratings. But they don't. So they have low bogey ratings along with their low CRs. In my previous post I should have said they have unrealistically low BOGEY ratings - which is what affects normal handicap golfers (ie. the overwhelming majority).
Yes, that's what I'm getting at.
Mind you, your course (which used to be mine) is short (~5800) and has a low CR (2 under par), but very few pros broke par in the pro-ams that were held during the 10 years I was there. So that would seem to suggest that perhaps short tricky courses aren't necessarily easy for scratch players.
I was referring to the CR which is scratch expectation.
No idea about slope. I have no idea how they work it out, because a bogey golfer might be an old boy who is short and straight or a younger player who smashes it miles but in the wrong direction.
