Not at all. I don't let you "get under my skin". May God help you to stop being the person that always tries to instigate under the guise of "but I don't want to be misunderstood" and your backhand insults. You go way out of your way to instigate trouble, and then make a post like above like you are so innocent. What a hypocrite! If this had been the first time you asked this question, fine, you are looking for an honest answer. Reality is, you have asked this many, many, times. Many times you have received the answers, only to scoff and not actually try anything. You twist things around to try and look like the little innocent one, despite a number of people in your threads saying you are full of it.
You don't like the pendulum, then don't use it. What is your motive in constantly trying to discredit everything the instructors teach? Why must you bring the same things up over and over? Do you get some kind of thrill out of it? Learn what you can to help your own game on here, and let it go at that. If you want to actually help others on here, then I suggest you first learn what in the world you are talking about instead of constantly putting out incorrect info.
And, we've had this same conversation at least 4 times already. So, I'm done with you. You aren't here to learn or to help, only cause troubles. Not worth my time anymore.
I am tired of your false accusations & foolish assumptions.
I quess that ruined my wish for you to have a good day.
Let us put this to rest here & now.
Explain how & why the cue tip will travel in a straight line for 2 or more inches when the forearm is moving in a circular motion as a radius does with the elbow pinned in a stationary position as the center of that radius.
How does one get any straight line movement out of a circualr motion?
What biomechanical mechanism would either allow or make that happen other than throwing the cue which would take timing to be accurate.
And don't say hang your arm down & swing it from a fixed elbow. That is no answer. In fact, that only demonstrates the issue.
If you don't understand the basic geometry & physics of the issue then you can not give an appropriate answer.
If you 'can't' or don't want to not give an appropriate answer for some other reason, then that is another issue.
I see no benefit to the pendulum stroke other than it is easier to
teach & not that it is easier to learn.
One can 'learn' to execute a piston stroke on one's own with no outside 'instruction'. It is simple. Simply move the cue & the tip connected to the end of the cue straight back & straight forward. The biomechanics required for that will happen naturally with no real thought needed if one's focus is simply to move it straight & not some other outside thought or focus. It is not complex & reguires no conscious timing.
Someone just PM'd me telling me that they wasted years with the pendulum stroke only to find success when they went to a pistion type stroke.
It can be done with or without any wrist involvement. It can have one more moving part or not. A lever is one of the most simple machines but it requires two parts. It requires the folcrum & the lever arm.
If you or anyone can reasonably explain to me how & why the cue tip moves straight for two(2) or more inches in a pendulum stroke, as was asserted by randyG in the other thread, which brought up this whole question in my mind, then perhaps my opinion of the stroke would change.
To my knowledge I have only asked this specific question twice in the other thread with no response & by starting this thread.
If there is no reasonably logical biomechanical answer, then so be it. It is done with smoke & mirrors.
If the SPF pendulum stroke is so good it should be able to stand up to a little scrutiny. In fact, it should be welcome so as to give an opportunity to display it's benefits. I personally only see one benefit & that is that it can be taught rather quickly & easily. But apparently there is a secret that I & others here on AZB are not allowed to know.
If that is the case, fine, then just say so.
The truth, the whole truth, & nothing but the truth is all that I am asking.
I am not trying to discredit any instructor. Instuctors, coaches, & teachers perform a great service to those that need help. That being said, there is one instructor that I do not care for due to a personal character issue that I found distasteful. That has nothing to do with my opinion of the pendulum stroke. It is just a coincidence that that instructor advocates it.
So...explain the assertion & show me the light.
If that had been done in any of the earlier posts of this thread it would most probably be over & you would have never gotten involved & turned it into the drag out that it has become.
So, I hereby request that the thread be closed as it has become obvious that there will not be any reasonably logical answer to my question.
