if you mean the cue ball hitting farther away from the corner pocket on the short rail
thats speed dependent as a variable as the harder you hit it
the cue ball will travel down the tangent line farther before the follow kicks in
so its a balance of how much follow and force
I get the "high action" or good topspin, whatever it is called. Mostly I miss making the object ball. This doesn't happen with power draw since the cue ball comes back away from the pocket.
It is like my conscious mind picks the aim spot but my sub conscious is afraid of the scratch so something causes me to over cut. I can do it fine on very short shots and soft to medium shots but as the force increases or the distance is greater I so something in my stroke that adds just enough angle that the object ball touches rail and I miss the shot.
I don't know if it is stroke, aim, or stance (I might be leaning a little without meaning to). But I guess the cure is the same. Progressive drills with increased seed and distance.
