usetobe,
I am much like you regarding precision & trying to me as precise as I can.
I had seen Bob Jewett's chart tracking the tip movement for a fixed elbow stroke as a series of arcs.
RandyG made an assertion that there is a 'sweet spot' in a fixed elbow pendulum stroke where the tip travels straight for several inches.
I asked how so.
From oldschool's CAD print out we see that indeed the tip does travel on a series of arcs & not in straight line. His print out is of a different variety than Mr. Jewett's chart & seems to relay less deviation than a perception given Mr. Jewett's chart.
I have now said several times that I can accept one saying that that is 'nearly straight'.
I would not accept if someone wanted to say that it IS straight.
So...can we now direct the attention to the original question with a slight modification?
How does one get the cue to move 'nearly straight' in a fixed elbow pendulum or what causes it to do so?
Regards & Best Wishes,
Rick
PS I'm sorry that I started this post to you & then went into a general type post. However, I thank you for your post & I thank The Renfro/ Chris for his as well.
UNFRIGGING BELIEVABLE!! Way to backpedal when you get caught red-handed with your hand in the cookie jar Rick. Do you REALLY think those involved for the last year and a half are going to suddenly forget? Do you REALLY think you can type pure B.S. and get away with it all the time??
Here's the truth- and if anyone doubts it, they are free to go back and check and prove me wrong on it.
Randy G. stated that in a pendulum stroke, the cue will travel straight for several inches. He calls that the "sweet spot". After that point, the cue will rapidly dip to the cloth. Before that point, the cue will be traveling on an arc. (now, ANYONE with an ounce of common sense, that is trying to learn something, that isn't trying to nit-pick, takes "level or straight" to mean "close to" not "has to be zero deviation, not even two hairs width".)
That Rick took the meaning the same as it was intended is obvious by all his past posts up until a few days ago when his theories got blown out of the water. For all this time, he has argued that the cue MUST travel on a pendulum path just like a clocks pendulum does. (His words) And that instructors are misleading students just for the money (again, his words).
Long ago, he was shown videos of how a pendulum works. He then decided that rather than admit he was wrong, he would change the definitions. If a stroke does not act like a clocks pendulum, it is not a pendulum stroke, and the instructors are still deceiving their students. It has been explained to him hundreds of times and hundreds of ways by many people that it is called a pendulum stroke because it resembles a pendulum, not because it acts exactly like a pendulum. He then wanted everyone to rename the stroke because it is deceiving, and if we didn't rename it, we were all deceivers.
Even in the other recent thread, the one with the poll about the pendulum stroke, Rick was proven wrong yet again. I supplied my own video, with instructions on how to view it to see what was there, and he refused to view it. When he finally did, he dismissed it saying it showed nothing. Still claiming that there was a large arc to the stroke.
Then Greg made his little contraption and to his surprise, found out that there is indeed a significant distance that the cue does travel along a straight line and not on a large arc. That is when Rick, instead of admitting he was wrong, went into nit-picking mode, and claims the line is not laser straight (what stroke is??) so he is not wrong.
Rick: 1.cue must travel along a large arc to be a pendulum.
2. cue has .015" variation, so it is not straight.
3. I win, instructors are deceivers and not to be trusted (again, his words)
4. Since the cue has to travel on a large arc, at contact you will be hitting on an uspswing which will alter the path of the cb.
Myself and many others:
1. Pendulum stroke has a distance where the cue travels straight, not on an arc.
2. .015" deviation is extremely straight when it comes to a pool stroke.
3. Instructors are not deceivers. They provide proper, accurate information that when applied will help ones game improve.
4. The cue does not travel on a large arc at all.
Oh yeah, Rick also demands a detailed explanation of how the cue can go straight. He also has been supplied with that many times over the last year and a half, yet dismisses all of them, and says no one has ever given him any kind of explanation.
Rick has used the pendulum stroke nonsense to try and debase instructors since he has been on here. There are two instructors that Rick likes, everyone else is "fair game" to him. A couple of instructors, and a few others, decided individually that instead of just standing by watching a wrong being committed, they were going to stand up for what is right, and not allow Rick to dispel his false accusations all the time and mislead others by them. That should get everyone caught up.
