Center to Edge Aiming – CTE.
In order for me to discuss this method I would like you to bear the following in mind:
Center to edge aiming is one of the most contentious aiming systems. It seems that people either love or hate the method and go to great lengths to argue their point. If an aiming system works for you then use it, if not then use another of the many methods.
So with that being said let’s look at CTE.
Center to Edge aiming has been developed over the years by the renowned coach and player Stan shuffett. Stan originally got the idea from Hal Houle who developed a number of aiming systems over the course of his lifetime.
Hal called it his three angle system.
Stan has worked on the center to edge system over the past 10 years and refined it into a method called “Pro One.” Stan has rigorously tested his method on a the practice table and in competition.
Stan’s Fargo rating is currently around 725, so he is a solid force to be reckoned with on any table.
Pro one is based around the geometry of a regulation pool table and its relationship to the angles 15, 30 and 45 degrees. Those three angles are not the same as those used in the quarters system ie. 1/4 ball, 1/2 ball and 3/4 ball.
The Cue Ball.
The cue ball has a vertical center line running between 12 and 6 o’clock and two extreme edges at 3 and 9 o’clock. Although there are no actual edges on a sphere these edges are a perception, semantics are not relevant to this system. The Edge that you perceive is the edge used for this system.
The Object Ball.
Visually the object ball is divided into four quarters each measuring 9/16″. The old Centennial balls are marked at the quarters to help make practice a little easier.
If you don’t have a ball with the correct markings then there are plenty of practice balls out there or you could use a marker pen.
