Patrick, thanks for your response. This is the article that I think I am misreading.
This from Dr Dave's site and refers to Diagram 3 which I could not copy to this post. I am referencing Case "C".

“Squirt – Part IV: BHE, FHE, and pivot-length calibration”
In Diagram 3, three cases are shown: “A, “B,” and “C.” Case “A” corresponds to a bridge distance shorter than the natural pivot length. The pivot angle of the cue is too large, as compared to the squirt angle, and the CB goes left of the centerline as shown in the diagram, causing the OB to go right of the centerline. In this case you need to move your bridge farther away from the CB and try again. Each time you move your bridge, mark the new location on top of the shaft with a small piece of tape or Post-It note. Case “B” corresponds to the bridge distance being exactly equal to the natural pivot length of the cue. In this case, the pivot angle exactly cancels the squirt angle, and the CB and OB both head along the centerline, ignoring throw for now (see the next paragraph). So if the OB heads straight, then the bridge distance (or grip distance) is what you want to use when applying the BHE (or FHE) method. Case “C” corresponds to a bridge distance longer than the natural pivot length. The pivot angle of the cue is too small, as compared to the squirt angle, and the CB goes right of the centerline, causing the OB to go left of the centerline. In this case you need to move your bridge closer the CB and try again. If you keep adjusting your bridge location, eventually you’ll see case “B” and you will have found the natural pivot length for your cue
