Well this is the crux of the issue. You say that every shot is a unique visual. Yet, in every description I've seen of CTE, including Pro 1, the specific positions of the CB, OB and pocket serve only to determine which of the secondary alignments and right or left sweeps to choose. Once this decision is made, you could place the pocket in your car, travel five miles down the road, and then lock it in a safe. The same with the cushions or anything else that might provide visual clues as to the direction of the pocket. At this point, CTE declares them irrelevant by providing no additional specific instructions to select one cut angle from the range of cut angles lying within the scope of the alignment/sweep combination chosen. It is just you and the cueball and the object ball and the visual references connecting them, all else be damned.
Consider an imaginary line connecting the center of the CB and the center of the OB (line-of-centers). And let's say the centers are 18" apart, just to fix it. In order to generate some specific cut angle then, you have to propel the cueball down a line (aim-line) which is at some specific angle with respect to that line-of-centers. Each unique cut angle requires a different direction relative to that line-of-centers. But the visuals described by CTE Pro 1 take no account of them. For a given CB-OB separation (18" here), the edge to point A reference, for example, is always the same. That is, it will always be at the same angle relative to the line-of-centers for our given CB-OB separation of 18". This applies equally to the CTE reference line. You cannot extract information (clues) as to where to point the cue from the same reference lines for different cut angles. Therefore, the edge to A and CTE references can only be used to generate one unique cut angle. One and only one.
We're assuming, of course, that you're being perfectly consistent with how you use those reference lines to position your head/eyes and eventually point the cue. There are three ways to be inconsistent:
- Random variations (we're not machines). Does this require any discussion?
- Explicit instructions. CTE doesn't provide them and explicitly rejects any further information that they may act upon (the pocket and rails are locked away in a safe). As such, sans the instructions, CTE is not systematic.
- Biased deviations. In other words "feel adjustments" or perhaps what Stan calls "visual intelligence." Yet another name for it is "your old aiming method."
