You've noticed, then, that this happens pretty much only at Kiawah. Simple reason for that is that Kiawah was the first course made available for stroke play. Call it a lesson learned...at Kiawah, they only took a couple hundred pictures around the greens. Since then, they have taken about double that number, which is why you don't see the odd angles much anywhere else. 200 or so pics just didn't cover the entire 360-degrees around the hole.
It's been like that since the beginning, and I would imagine will always be something we have to deal with. I just don't see WGT going out & re-taking all those pics again.
