On his recent DVD, CJ put a number to his TOI -- 1/8th of a tip (and by "tip" I imagine he meant the full cue tip width rather than just the (smaller) tip contact patch). Since most tips are about 1/2" in width, 1/8th of that is just 1/16". Do you believe that most good players' strokes are always accurate within 1/16"?
I think CJ put a number on it because he was some what pressed to do so by the vagueness of the term 'touch'. As CJ just said in his introduction to his TOI Video, his goal is to get 'us' to develope a 'feel'. I do not & never have taken a slide rule or calculator to the pool table with me when I'm playing pool. All I can tell you is about my experience, which is, I have never, to my knowledge, hit the opposite side of the CB that I intended to hit. I have very much confidence in what human beings are physically capable of doing with their amazing make up of body & mind if they can just keep their brains out of the way. Over analysis almost always results in either total or partial 'paralysis'. Perhaps too much knowledge of specifics just puts fear of failure into the picture.
I've been wondering when BHE would be brought into the discussion. For a good many shots, if one bridges at the shaft's natural pivot point and then strokes crooked -- unintended back-hand english -- the CB still tracks on the intended line of the shot. So if the initial aim was sound, the ball still goes in. Your comment about speed of shot does have some validity in this, however. So does CB/OB separation.
So...in this case, if one mis hits & still pockets the ball, it would be luck, unless they set up & shot as for BHE while still trying to hit center & as you say speed & seperation are key factors. I doubt if many are going through the trouble to take out an isurance policy for all of their intended center hit shots. If so then the speed of shot is limited. Also as you say the initial aim still needs to be sound. What if the aim is off center to one side of the pocket & then the mis hit causes the CB to contact the OB on the other side? Very much more than likely a mis would be the result. Obviously in any plan of operation the initial aim is a crutial factor. But with TOI one side mis is all but eliminated. I can & have aimed to mis the pocket & then deflected the CB to cut the ball into the pocket. This is part of what CJ is referring to when talking about position options without spin.
But, now, compare the difficulty of sending the CB on its intended path in the manner just described (bridging at the pivot point and planning to hit center CB) versus using a TOI at varying CB/OB separations. For example, let's assume the two balls are 2 feet apart and we are cutting the OB to the right. Further assume that we need to squirt the CB some small amount over that 2-foot distance, let's say 3/32", to pocket the OB center pocket using TOI. Assume we do that perfectly.
Now move the CB back 2 more feet, but on the same line to the full-hit-ghost-ball position as for our shorter shot. Now we need to squirt the CB 3/32" over the 4-foot distance. Will the same CB hit (contact point, cue stick angle, shot speed) do that? Won't the CB deflect a lot more over 4 feet than it did over 2 feet? Do we have to worry about swerve yet? Do we now need to squerve it 3/32"?
Now move the CB back 2 more feet on that same line. Now we need to move the CB 3/32" to the left over a 6-foot distance. Surely swerve is coming into play by now. Will the same hit on the CB work?
Please re-read my 1st paragraph. But let me ask you a question. Do you test the friction of every table cloth that you play on & then calculate the rpm spin to speed ratio required to draw a CB back 4 ft. on a full hit from an OB that is 6 ft. away and then re-calculate them again for a different set up? Do you actaully do that? Or do you rely on your perception based on past cause & affect & just shoot the shot?
To use the TOI/3-part pocket system do we have to become cueing savants to get the net effect of squirt and swerve to put the CB in the right position at all the possible different distances between CB and OB? Can simply angling the cue a fixed, small amount (rather than holding it as level as possible) accomplish that?
Does TOI really simplify life? I see it as potentially highly beneficial for its effects on the CB after collision, if one prefers to play position in that manner, but I'm not yet sold on its other claimed benefits. I look forward to hearing more in CJ's TOI video.
There's that word again, 'savants'. As I've said, IMHO the human being is an amazing biomechanical machine but with a conscious & subconscious mind. Humans can conceptualize, have a percerption, & develope 'feel'.
If you want to match up a calculating brain type player & a 'feel' type player, I'm betting on the 'feel' player. Why does anyone practice if all that needs to be done is do the calculation in one's brain, or with a calculator, & then execute the shot. One develpoes 'feel' by experiencing repeated cause & effect. I 'know' how much a certain off set affects the cue ball, but I do not say to myself well I need 1.5 tips which in x" so hit it there. I do it by feel based on my experiences with cause & effect. Now that being said, the numbers knowledge can give one a fairly large head start on developing that feel through a good approximation as to what is needed.[/QUOTE]
Mr AtLarge,
Thanks again, for the opportunity to make my opinions known again. I cetainly do not have all of the answers, but I know what works, at least for me & some others. I hope no one in my pool room ever finds out about TOI & if they do, I hope they never take it to the table to give it a try, & if they do that, I hope they give up on it after the first ball that they mis & say to themselves, TOI is just too complcated, the same way so many say, 'I just can't play with english, it's too complcated'.
Regards & Best Wishes to You &
