I don’t believe that for one second. When I walk the dog down the rail I’m so far on the edge. It takes a soft hit not to miscue.
I just realized what you said about the extreme edges with spin and the "walk the dog" shot.
I agree, my experience says that miscue limit is not accurate for some types of shots.
I, like most any experienced player, would never want to spend much time close to that CB area but I have/can certainly go there without any worries about miscues as long as I use a specific type stroke at a specific speed not to mention, at a specific speed.
When I use that area of the CB, the stroke I use is not what I would call "easy". When I shoot that shot I would call it more of a "rub" or even a massage rather than a "soft" hit..... almost like a push-through stroke but without fouling.
I know you understand what I'm talking about because you brought the shot up.
To give others an idea, it's the very same stroke I use when kicking the CB at the corner pocket on a 9' diamond pro-am with "VERY WORN CLOTH" while on the 140/70 track line and using a measles ball.
On worn cloth and on that table, that particular shot can be very difficult without adjusting to another number such as ~140/67 to ~140/69.
That is one of the shots I go to if I think my stroke needs tweaking for touchy draw/stun shots.
