Good post...and so true. I know I see "pool" differently now than I did a year or two ago (which was WAY different than how I viewed it 15 years ago).
I pretty much look at a shot and think--- "Oh-- just hit it this way, make it, and come around to this point" like it's no big deal... as if it is expected. Years ago, I'd look at the same shot and think how immense the distance between the CB/OB was....how tiny the pocket looked....how I had to get lucky to hit it perfect.
Perception is everything in pool.... and it's a developed ability. I think that's why some people never get better after years of playing.... they never learn to perceive the shots correctly.
SWC,
You neglected to say that besides how tiny the pocket looked...how tiny the OB looked as well. But you could still see the center of the small looking OB from that perspective while behind the CB setting up for that shot.
You could also see a spot between the center of th OB and the edge on the equator that some call that 1/4 OB. These I accept are points of interest (edge, center and 1/4) that Hal taught from what I have read read posted by those that learned from him or those that did from others.
You could look closely at a spot between the 1/4 ball and the edge of the OB on the equator that some call 1/8 ball....which could be a fourth spot.
I have followed CTE threads that requires a parallel shift away from the CTEline (CTEL)...there are other ways to set up for the pivot (prepivot).
I have read that some feel more comfortable, visually, using the edge of the CB and not it's center. Some here that use the edge of the CB also mention that they reference that edge to the 4 spots mentioned above on the OB.
I am convinced that both have value for the reference points ala center or edge of the CB aimed at the edge of the smaller appearing OB is the origin of the shot. I tried different parallel shifts to the side of the CTEL, many were metioned, and many didn't work for the same cut angle at all distances between the CB and OB.
It wasn't until I surmized that a shift from CTEL to the center of the OB from it's edge was a smaller appearing distance on my "focal plane" as the OB appeared smaller and smaller as the OB was farther down table. I got down on the table without a CB and started to parallel shift my cue tip from the edge of the OB to it's center of the smaller appearing OB at various distances.
Sidebar:
If you look through a window (focal plane) at a car parked across the street and drew with a crayon on the window the diameter of one of the tires, the circle that you drew would be smaller than the actual tire. The distance from an edge of the tire to it's center would also be smaller...and the 1/4 and the 1/8...
It wasn't until I ignored the relative points on the CB that I started making progress. This was when I realized that I could use a non parallel shift that I called "aparallel" shift of the cue shaft, say to the center of the OB, without referencing anything on the CB...except the pivot back to the center of the CB. When I did this, I started getting the same cut angle with the same 12 inch bridge distance behind the CB regardless of the separation between the CB and OB...except when they were very close to each other.
This was also true when I aparallel shifted 1/4 ball inside of the edge of the OB....and true for 1/8 ball.
I was able to get:
30 degree cut with no shift from the edge of the OB
~45 degree cut with 1/8 inside of the edge of the OB
~60 degree cut with 1/4 inside
~85 degree cut with 1/2 (center) of the OB.
I, being able to recognize the angle from the pocket to the OB to the CB am able to adjust these 3 shots thick or thin for other angles from 30 to 90 degree cut angles.
I believe that Hal recognized the angle to the pocket and adjusted the shot for that angle and without looking at the pocket after deriving the angle was able to pocket the shot.
If the shooter's bridge distance is different than 12 inches, the the results will be plus or minus a few degrees.
Thanks for this an other threads and PMs that lead me to diagram CTE and it's derivatives in AutoCad and time at the table.
I am not comfortable with the steps that CTE requires to begin and when you spend hours using it, it can become intuitive and like other "systems" of aiming...you might get into "dead stroke".
I didn't address shots from 0 to 30 degrees for I find double the distance aiming easier for me.
Thanks for reading.:smile::thumbup:
