this diagram doesnt mention a clock but you can "see" the info
View attachment 774226
I was completely unaware of the existence of this diagram. Was there any additional explanatory text. Tell us the details where you found it and any other information you have.
I note that you stated that there was no mention of a "clock." Without utilizing this precise clock reference as I explained it, although the "info" is presented, at most, that is all it does. Agreed, it does present similar significant details and relationships. In this case, that is still quite a lot.
Note that from 12 Noon to 3 PM is not only 90 degrees. It is also 15 minutes and even more precisely, 900 seconds. Being able to reference degrees or time on the outer edge of the object ball allows for maximum possible precision in using the technique/tool I describe. In time, practicing using this technique/tool will evolve into feel. A feel easily and directly acquired using this clock method of determining the precise contact point. A feel that won't take 1000 repetitive practice shots.
If one were left with only the diagram above, yes, it is intriguing, more than that even. But to my mind, it suggests one would have to memorize the specific lines, angles and points and their relationships depicted to make use of them. There is no deeper exploration of the fundamental concept. What to do if the angles desired are not exactly as depicted? Obviously, you are only left with the option of making intuitive estimations. In other words, the diagram alone is "piecemeal." I hope I'm making sense.
The description I explain of how to determine the exact contact point can account for any and all contact points to achieve any cut angle. You do not have to memorize any specific lines, angles and points. You are free to clock reference any point on the outer edge of the object ball.
Our understanding can not only be determined by what we learn but also by how we learn. In this case, did you learn by the diagram first then by my explanation. Or did you learn from my explanation then by the diagram. Is there any concern to judge whether which or whose idea deserves more credibility and therefore merit? Remember, I posted this technique/tool as a "promo-tease."
I don't mean to be repetitive. Maybe I am splitting hairs?
Nevertheless, it is good to see that no one has disputed anything I described/explained/claimed regarding precisely determining any contact point. And no one has described a simpler more easily understood and versatile method as of yet.
Although it is not exactly the major slam dunk I had hoped for. I'll take a swish any day.
There is no question that there is information in this diagram that coincides with what I described/explained/claimed.
