Does that include, 'Electronic witchcraft?' I couldn't resist. JK.
Testing Your Stroke

Absolutely, especially digital cue ball witchcraft!
Let’s do this. I’m planning on making pool and carom size digiballs. When they’re production ready I’ll send you one and you can use your knowledge to test it’s accuracy.
I'm 78, don't take too long! LOL!
Thank you for the list.
I've been pretty much exclusively playing 3c when out for the past few years and the guys who play 3c well are constantly reminding me that I hit the ball like a pool ball.
Strokes exist in 3c that don't produce the same effects when imparted upon a pool ball.
Truth.
Yes.
I would like to challenge Bill to provide a video of the same shot with a video perspective from the side that shows his cue being level.

I guess you could be doing it on a table where the spot had been mis-placed (intentionally or not) off towards the rail, but udderwise I think it's a no-go.

With some careful reading You would have seen this video is from 9 years ago.
I haven't stepped into a PR since 12/2019, I doubt I'll be going anytime soon.
Besides, I doubt there is an extra trash can available!

Show Anyone here were I EVER mentioned the word pertaining to "My" video level cue?
BTW, with the CB frozen to the cushion a player and not contact the CB on the 'Horizontal center line.'
I know -- I'm, pretty sure you posted the same video on the 1pocket site some time back, so what.
Listen, you gave me grief about posting up a video, saying, "A picture is worth a1,000 words. Video is worth 10,000! Anyone can spew words!" So I say to you: A picture is worth a1,000 words. Video is worth 10,000! Anyone can spew words!
Post it up and let's see your perfect stroke that does not quiver off line. I think you need to put some masse on the shot, not any kind of so-called perfect stroke.

The video doesn't lie! My cue goes 'Straight-thru' like an arrow from a bow!
However, Your cue flies up like an elevator.
Slow mo the vid All you want, it won't change. Don't believe your own eyes.
If I don't go to the PR for my own reasons, why in the world would I go at your behest! LOL!

Clearly, as shown in post 83:
Testing Your Stroke
Here's a situation where a player can test their stroke. The scenario is, playing 1 pocket, you have the upper left pocket, You need both balls. The cue ball is frozen on the long cushion at the 3rd diamond, 9 ball is on the spot and the 15 ball is frozen on the 1st diamond by your opponent's...

Your cue does not go straight through, lol.
And all I’m pointing out is, you issue challenges but have excuses when they are issued in return.
Lou Figueroa
For All to see, we Know Yours did NOT go straight-thru!
No Blur of the cue in the video or 'Flying up of My cue.
I didn't 'challenge' you or anyone else! ll I said was I'd like to see a video someone else executing the shot.
I saw how You 'execute.'
So my cue went up, BFD — your cue went sideways.
There are all kinds of strokes out there that get the job done, including your sideways, shooting down, bouncing the CB stroke.
Just don’t try and sell it as anything else, puleeeezeee.
Lou Figueroa
I will admit, you're good with words, PERIOD!
Someone questioned the positions of the CB and OB being 'Tweeked.'
This snapshot will show the positions.
This snapshot will show the positions.
This thread was very good for me as it helped me re-organize my definitions. This is actually hard to define.
Please let me know if you agree with the following:
A "stroke" is the combination of the following components:
1. Speed
2. Acceleration profile
3. Path of the tip
4. Bridge length
5. Nominal effective end mass of cue
6. Coupling of the mass of your arm to the cue
7. Follow through length
This allows for a tremendous variety of different strokes.
The time that the tip is in contact with the cue ball is about 2ms at most. This means that #2, #3 and #7 has negligible contribution to the interaction during the 2ms contact time, due to the very small ratio of contact time divided by the acceleration and velocity of the cue. Hand-roll that affects tip yaw angle also is negligible due to the ratio.
The coupling of ones arm to the cue MAY affect the end mass. I say may because I am not certain this is true, I need to do more research. The bridge length also affects the effective end mass. Therefore the combination of #6 and #7 may contribute to variations of effective end mass.
Therefore,
A cue ball interaction is the combination of the following indivisible components:
1. Speed
2. Cue angle (pitch and yaw)
3. Cue tip location (x and y coordinates relative to center of cue ball)
4. Contributive end mass of the cue
So this means that a stroke can only affect the ball in the above four ways.
As I said, it may be possible to hit the ball with the exact same speed, cue angle, and tip location, and change the squirt with different bridge lengths and grip strengths to achieve different cue ball paths, but I am not sure to what degree.
However, does anyone believe I missed anything on this list?
If you want to dismiss this effort because you do not see value in analysis than I kindly ask you don’t reply. Thanks
