Yes the cue was 19oz. I didn't personally put it on a scale, but it was labeled 19oz when I bought it.What weight was the cue?

This may be one of my favorite Dr. Dave videos of all time.
Excellent work Pubo and Dr. Dave!
I've been trying to communicate exactly what is shown in this video forever, but I don't have the articulation you do.
Being a professor definitely does help!
Good question that I don't have an answer yet. It could be due to my counting. I'll think about this and get back to you.Thanks for the video. On the tip contact time plots, I noticed that there was a lot of variation in contact time near the middle of the graph. Do you know what caused this?
FYI, I just posted a new video that shows and discusses results from a careful slow-motion-video study debunking many common myths concerning draw shot effectiveness related to stroke acceleration and timing, and tip contact time. Check it out:

Enjoy!
I haven't done this yet. Using the top edge of the shaft to approximate tip height is easy and consistent, but the actualy contact point varies non-linearly with this "tip height" because the tip is round. I might do some analysis when I got time. So far just by looking at these footage, I feel like speed has more influence than the difference in tip heights (which agrees with physics).Great video as always. And @Pubo thank you for the tedious work of collecting this data.
I’m curious if you have data on the impact tip offset has on the resulting draw, assuming an equal speed. How much difference would .1 in your ball scale make?
Great video, I’d like to thank you and Pubo, for the work.
I find it amazing that some people require so much convincing.
The original striped ball/chalk mark video should tell anyone all they need to know.
You have definitely laid it all out there, and greatly improved my experience, when drawing the ball, Thanks![]()

Dave,
In my experience, a draw stroke with better ‘follow-thru’ typically produces more CB action/distance.
How does that relate to your test results (?).
And voodoo.Good question.
Answer: Good stroke.
I can answer this for you, since I am a student of the game. This is a ticky with inside draw.And voodoo.
I wish there was a Dr Dave for carom games. Those balls do far more spectacular things than pool balls do.
Interesting. I never would have guessed that making a conscious effort to follow thru on your draw stroke might automatically increase cue speed. I wonder though, if someone making that ‘conscious effort’ might typically also have a natural unconscious tendency to simultaneously tense up their grip?That is my experience also. With a relaxed and smoothly accelerating stroke, a good follow through cannot be avoided. See:
It isn't directly related to the results, but it is certainly indirectly related. Acceleration at the moment of contact is not important, but smooth and complete acceleration during the forward stroke into the ball is critical. The cue speed required at impact automatically creates follow through, unless one tenses up the grip and artificially constrains the follow through.

I'm well versed...though I'm only a couple years into my capitulation.I can answer this for you, since I am a student of the game. This is a ticky with inside draw.
The player in this video hit the ball at about 7:00 o-clock, and "aimed for" the last portion on the short rail, by bending it, with so that he could double it with the inside spin. The draw bent the shot.
If you aren't aware, there is a big difference between pool table rails and cloth, and that of carom tables. Pool table rails are very soft and the cloth has more friction. Carom rails are made of harder rubber and allow the balls to retain more of their initial spin after the collision. The time that it takes for the table friction to change the ball paths are longer (a lot more slide), so you can play for reactions like this after multiple collisions.
Believe it or not, though this was a very well executed shot, this is also a reasonable solution and isn't rare to see.
Another common way to play this is with 11:00 English and no ticky, long rail, long rail, and short rail right before the red ball. Top bends the ball after one collision, and requires some feel also.
Not to turn this into a billiard thread, so I’ll just make one more comment. In case you are not aware, natural tickies off the long rail track to the head/foot spots. You can modify this angle with top/draw, as Mazin Shooni expertly showed me one time. It is great to know because you end up making a lot more points.I'm well versed...though I'm only a couple years into my capitulation.
Love those gdamn balls. It is a far better game than pool, I say.
I'm going to celebrate myself, in fact:
I played a hell of a ticky yesterday. I was absurdly close to red ball and could only shoot to Long rails or to the end ,toward ob2.
Ob2 was at the other end of the table, ~8cm up from the center. I kicked long rail and back to full on the ball I had been stuck on, then in/out of corner for two more rails and the score.
I was gonna yell but there was no reaction from the room, so...
