If you knew as much about CTE as you claim you wouldn't even bother making stupid posts like this. I can show you a position on the table where placing the object ball and cue ball are a perfect 30 degree perception, move the object ball 1/2 ball away from that position and it is a 45 Outside, yet another half ball away and it is a 45 inside, cue ball is same location for all 3 shots. These are positions I know, but the point being during play you cannot know exactly since a 1/2 ball or ball difference can make a big difference in the result so the obvious thing to do is use some other way to verify the shot looks on, no different than feel, ghost ball, or contact point shooters do. The reason CTE players practice it so much is to learn to KNOW the perceptions at a glance, not to make balls. If you use the right perception and the system as taught, you will make the ball. Some perceptions are very obvious, others are borderline at a glance to less experienced users. Most shots I miss were the wrong perception and I didn't verify before shooting.
For someone who thinks CTE is so bad you and your squad sure try to hold it to a high standard to try and disprove it.
