Don't know if this is on point for your question...
I wondered what CTE's "perception" would look like for exact fractional cuts (3/4 ball, 1/2 ball, 1/4 ball, 1/8 ball), so I made this pic to illustrate that from the perspective of the shooter after pivoting to center cue ball (CCB) for the shot.
The yellow lines are CTE's "perception lines": one from CB edge to OB aimpoints A/B/C - the other from CB center to OB edge.
The white line is the CB's path (which the shooter is looking straight along).
I'm not a CTE user. Maybe somebody who knows better can explain how these differ from real CTE perceptions for these cut angles. I guess one difference might be that these are after-pivot perceptions, maybe not the ones you should see before pivoting...?

The difference is that the fractional overlap is NOT the CTE perception. In other words there is no such thing as a CTE after pivot perception.
The CTE perception is done pre-pivot and after the pivot the only thing that the shooter is looking at is center ball down the shot line. And at that point the shot might be a 3/4 ball hit, a 1/2 ball hit or a 1/4 ball hit.
But pre-pivot, that is when the sighting is done standing up the CTE perceptions at that moment have nothing whatsoever to do with the fractional overlap at contact.
Here is a video where I took on this subject somewhat. (I wrote the angles backwards but the point should be clear.)
