My take on whether miscues or unintentional scoop shots should be fouls is simple, what are we realistically trying to solve? These poor hits do not create an advantage 99.999999999999999% of the time. We all know an intentional scoop when we see it and any arguement against this should also cast doubt on not requiring players to audibly call obvious shots.
This hasn't been an issue for nearly 200 years of competitive cue sport competition until some European refs (mostly with a snooker origin) got confused about the American pool rules and instead of learning, dug in.
I suppose you can try to set this new take on the rules but without a high speed camera on every table I doubt you'd get the average league player accept the foul ruling because it “sounded” like a miscue.
Simplest solution? Point these refs to the WPA documents. After that, replace the ref.
