Don't agree. Pattern play consists of managing both the angle and the distance from the object ball.
In fact, the greatest pocketers have almost never been the most precise pattern players for the perfectly good reason that they never needed to be and that, for them, it was not necessarily the best percentage.
The greatest pocketers were always willing to leave a little extra distance to make absolutely sure of the right side of the ball for the next shot. This style has sometimes been called "cinching the angle" and Strickland, Filler and Kaci all play/played that way because, for them, it represents the highest percentage.
Kaci doesn't play the position angles with the precision of Fedor Gorst and is not, on average, getting as close to the next object ball. If somebody asked me whose game, of the two, they should study to learn what almost perfect pattern play looks like, I'll tell them to study Gorst over Kaci.
Yes, Kaci's amazing, but he's not the best pattern player out there. Kaci's approach to running out is very similar to that of Strickland in his prime.
