Is the Object Ball just a "Mirrored Reflection" of the Cue Ball

I don't know if "IT'S" acceleration or not. One day I think it is, the next day I don't. Whatever "IT" is, "IT'S" the key to every thing, once a player reaches a certain level. Right now, provided the CB is off the rail a few inches and the cut is 30 degrees or less, I have EVERYTHING down, except "IT;" and some days I have that down.
"IT" is a "touch" that when produced consistently, delivers the exact same amount of spin on the CB when using "inside." This in turn produces the exact same amount of deflection on every shot. It's the final piece of the puzzle...the cherry on the whipped cream. Right now I have everything down as far as shotmaking with the exeption that I'm inconsistent with "IT." When I master "IT," I'll be a very happy camper! CJ Wiley claims "IT" is acceleration at the exact point of impact. Before I even read him writing. about it, I theorized the same thing. Now I'm wavering a bit; nevertheless, "IT" is real.

It's nonsense. Trying to increase acceleration at the moment of contact only encourages uneven acceleration - and has no positive benefit even in theory.
Your shaft produces the same amount of squirt for the same tip offset regardless of speed. Neither the speed nor the timing of the acceleration that produces the speed has anything directly to do with it. For longer and slower shots swerve is a factor, but you don't seem to be talking about those shots.
This is right, but I think you're overemphasizing the importance of acceleration. The important thing for the result is tip speed at the moment of contact. Smooth acceleration helps to keep your stroke straight and helps control the speed at contact, but doesn't matter otherwise - if you can produce the same tip speed at contact, it doesn't matter whether you're accelerating, decelerating or neither (in fact, neither is best for predictability).

Acceleration needs to continue AFTER impact!
EVERY great shotmaker will use TOI at some point! Whether it is for shotmaking or position play. Even I do not use it for every shot, but I do use it for many shots.
Maybe the only people that do not use TOI is those who think a low deflection shaft will make them better shotmakers!
Maybe, but the only reason for that is to ensure that acceleration is constant throughout the stroke (to avoid jerking). In fact, as DTL says, most knowledgeable folks say acceleration should plateau just before impact to ensure maximum speed predictability at impact.
Every player of any caliber will use inside, outside or neither depending on what's needed for the shot. A little inside is just another place to hit the CB - no need for special emphasis or a special name for it, unless you're in the business of hawking DVDs.

First of as CJ has said many time TOI is a way of playing its not referring to a touch of inside English ,, so yes there are several great shot makers who don't play with TOI
Next yes a low deflection shaft will make you a better shot maker

Yes, "acceleration" is mostly misunderstood and misrepresented in discussions of pool. Speed predictability at contact is the important thing, and that's best with a stroke that "coasts" for a short while before contact (this occurs naturally with a pendulum setup/stroke).
I think the word "acceleration" should be retired from these discussions because it's mostly misleading.

This seems to be true for many sports and games. A player begins learning to play by naturally holding the racket, club, stick, etc. and relearns the correct way as they become more serious about improvement. Being naturally comfortable rarely sends a player on the right path unless they're extremely gifted.

I like the thought of accelerating on most shots. It commits my stroke to be deliberate and not let any doubt change its direction at the last moment. I don't worry about inconsistency or deceleration. My thought is to accomplish what I started as the cue moves forward.

So you really believe it is NOT necessary to follow through with your stroke? The cue does NOT naturally re-accelerate after contact...there must be something propelling it! In accord with Newton's second law of motion, the acceleration of an object is dependent upon both force and mass. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision. The cue does NOT lose "speed", it simply transfers it!
That is why it is so important to accelerate through the ball!

Just because CJ has labelled TOI as a way of playing does not mean sidespin is not applied to the cueball. When you hit the cueball on either side it IS called English! I've been using a "touch of inside" long before CJ was born!
If a LD shaft makes you a better shotmaker, why is it over 60% of the top pros do NOT use them and most that do, do so because they are paid to use it?
Which, of course, means it loses it.
It's not at all important to accelerate "through the ball" - not to mention impossible. It's only important that your stick be moving at the correct speed when it hits the ball. Assuming it's moving at the same speed when it hits the ball, the cue could be swinging on a string or thrown like a spear and have exactly the same effect as if you "powered through".
It might be useful to "feel like" you're accelerating all the way "through" the cue ball, but that's only to be sure you aren't doing something that jerks your stroke offline (and maybe to be sure you hit the ball at the right speed).

The cue can be moving at a constant speed and still accelerate through the CB.
The CB is not moving, not spinning, not doing anything....it is just sitting their on its contact patch.
When the cue contacts the CB.....it is going going from 0 to some speed....meaning it accelerates even though the cue is moving at a constant speed. This means from the CB balls point of view, the cue appears to be accelerating as it stokes through the CB.
It is best to keep a constant speed as you stroke through the CB.
I got rear ended once while riding by motorcycle. I was hit at a constant speed, but since I was sitting still, I felt as if the car was accelerating through me.

The cue doesn't "stroke through the CB" and it doesn't "appear to be accelerating", it just appears to be moving at a certain speed. In fact, during the entire millisecond the cue is in contact with the CB, it decelerates dramatically.
The CB can't "tell" whether the stick is accelerating, decelerating or neither - only what speed it's moving.

1. Duh, how did it do that (undergo a change in velocity)? By definition to "undergo a change in velocity" is to accelerate. Therefore the cue DOES accelerate after contact!
2. Of course it is needed to make the shot. The cue ball has no forward momentum without the application of force. Since the arm and cue have more mass than the cueball, it would be virtually impossible to prevent the follow through! Therefore "technically" speaking it IS needed to make the shot...unless you found a way to circumvent Newton's Laws of Motion!
3. Where did you go to school?

PJ you are so wrong...you simply do NOT know what you're talking about. Go back to physics class!
A change in velocity is acceleration, it doesn't have to be constant, and doesn't have to be equal, and it doesn't have to be in any direction!
"Any change in the velocity of an object results in an acceleration: increasing speed (what people usually mean when they say acceleration), decreasing speed (also called deceleration or retardation), or changing direction. Yes, that's right, a change in the direction of motion results in an acceleration even if the moving object neither sped up nor slowed down. That's because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction. Thus, a falling apple accelerates, a car stopping at a traffic light accelerates, and an orbiting planet accelerates. Acceleration occurs anytime an object's speed increases or decreases, or it changes direction."
Just because the cue contacted the cueball, it does NOT stop accelerating! When the cue is no longer in motion, THEN it can no longer accelerate!
