Some engineer types believe that although (left edge), "A" (1/4), "B" (1/2), "C" (3/4) and 1/8 on the OB are constants and will appear on the OB in the same location for every shot/angle as though it were a printed disk, we know that those fractions define different points on the circumference as the cut angle changes even though the image is the same.
In cutting to the left, if we aim the left edge of the CB at the left edge of the OB, we will be close to a straight in shot or a thick cut angle (CTC).
If we want a thinner cut angle, we can aim the left edge of he CB toward "A" 1/4 ball and be close to a 14 degree cut.
For an even thinner cut, we can aim the left edge of the CB at "B" 1/2 ball and be close to a 30 degree cut (CTE).
For an even thinner cut, we can aim the left edge of the CB at "C" 3/4 ball and be close to a 50 degree cut.
For an even thinner cut, we can aim the left edge of the CB at the right edge of the OBl and be close to a 90 degree cut (ETE).
With time at the table (many hours), one can see the relative locations of the pocket/target, OB and CB and recall where on the OB to aim the edge of the CB. I can do this and can make adjustments for the angles in between the fractions with my cue tip a bit to the side, top, draw, inside and outside English.
Eventually, I don't even think about fractions for I see the shot at hand while standing and move into the shot from memory. This happens to me with other aiming systems and I can rapidly capture the solution almost instinctively...like being "in the zone or dead punch".
I understand that what I described isn't CTE/Pro1 but it is also why I know that it works.
I saw this reality with Hal's CTE years ago.

Thanks and I agree with you.
