I guess I need clarification with regards to the 9B break shot.
On all my Accu-Stats videos from the Sands Regency Tournament back in the 1990s and the U.S. Open videos from the 1990s and from what people told me back in the day it seems like the plan was to squat the CB. Leave it somewhere around the middle of the table if at all possible.
Is that not what players are trying to do nowadays?

Before WNT when the 1ball was on the spot and before special gadget for racking, that was the goal, a stop shot on 1ball from the rail head on that would make the CB jump up and land in the middle of the table and make a wing ball. The 1ball will go towards the side pocket, sometimes will go in, sometimes will hit the rail bellow the pocket and hopefully leave a shot on it to the corner.
When racking gadget started to pop, players found that they can get the same result and more consistent with a soft break.
Some used a cut break to try and make the one in the side.
With today's 9ball on the spot:
1. if a box is used then you go for a cut shot to make the one in the side, you add some draw to get the CB to hit the side rail and go back to the center table. some add some side spin so the CB will hit the 9ball and try to make the 9 in the side.
2. if no box is used, then it's back to the big head on shot from the side rail. two balls will go towards the corner of the same side of break, the one ball will hit the side rail and go towards the bottom corner on the side you broke from. This actually and easier and more consistent layout to run out than it used to be with the 1 on the spot....
