What happened to contact time is so short that increasing it doesn't matter?

An almost 2x contact time doesn’t matter until it doesn’t.

All this talk about being scientific has me wondering about what I've been wondering about for a while. How was the fact that deflection is the same no matter how hard you hit the ball proven. ... What type of tests prove that fact or is there some basic physics involved that I'm unaware of. I'm unaware of most physics so there's that.
So you need to minimize swerve in the tests. Maybe be sure your cue is level as possible and you're hitting right on the equator...?How was the fact that deflection is the same no matter how hard you hit the ball proven. I get the point that it's that the swerve counteracts the deflection so a softer hit seems like it's less.
It has been proved with math and physics (for the few who have the necessary background and who actually care) here: TP A.31 – The physics of squirt. It has also been proved with careful experimental testing (with a cue testing machine and a human), documented in the articles linked here:

Sometimes the effects cancel. The worst combination is a soft tip that is dense/heavy. For more info, see the section at the bottom of the page here:
Yeah, the (for the few who have the necessary background and who actually care) was a little over the top.Any chance you could be a tad more condescending?

just checkin’
I like to keep things the same. (Less variables the better). I have one shaft with hard tip (put on new few weeks ago) that I never used before this video and all my other shafts (for playing and breaking) have actually the same tip. (Only exception is my jump cue with a phenolic tip). My break cue was my playing cue for over 15 years and it feels the same as my playing cue.
My draws (quality and control) are quite bad. That's the reason I couldn't beat your 93 from Exam I yet.
(I did catch a cold so please excuse the sniffing sounds in the video, but I still wanted to include the sound because of the differences of the 2 tips.)
first tries are with the new hard tip. Last 3 are with my regular shaft and tip.
I do prefer the sound of my regular tip and it seems like I have a little better control with my regular shaft (but this could be the difference between the shafts. The one with hard tip is 314 first generation and my regular shaft is 314-3 generation. But yes, no difference in draw quality. If anything, harder tip seems to generate the draw easier. (I did miscue once with the harder tip. But I miscued like 300 times with my regular shaft on this shot over the last two years.)
Thank you for posting. I wish other would do this too, or at least try the various tests I have shown, so they can see actual results on their own.
Your draw action was definitely not "quite bad." In fact, I think it looks quite good.
Your results are certainly in agreement with mine; although, I was more sure I got better action with the break cue (especially after I did more comparisons today).
did get better action than expected. But totally mishit the object ball every time. Tried to replicate same shot from your video, so tried to draw to the path of where my cue ball started. Did accomplish this 2 times with my regular shaft but hit way too much left or right with the other shaft with hard tip.Your draw action was definitely not "quite bad."

I aint buying this. How do we know that you didnt rotate new and used pool table cloth in for these tests? Maybe you took 1 shot then put new cloth on, took another shot on the new stuff and changed it back? You could have been swapping tips on the break cue or maybe you even had a stunt double cue with a soft tip. Regardless of your proof I just know that soft tips = more spin and hard tips = less spin. Everyone has known that forever, just look at the contact time, 30 seconds for a soft tip and .008 thousandths of a second for a hard tip, there's just no way a soft tip doesn't produce more spin.Here it is:
Enjoy!
Now you know what it feels like to be US. We've been asking others to try a certain something between CB and OB so they can see actual results on their own for 25 years and it's fallen on deaf ears and NOT tried. The aftermath has also remained the same.Thank you for posting. I wish other would do this too, or at least try the various tests I have shown, so they can see actual results on their own.
And a juiced CB?
I edited out the parenthetical. It wasn't necessary and I worded it poorly. What I meant was: Only people with strong math and physics backgrounds would find any interest in my technical proof analysis; and among the few pool players who actually do have the necessary math and physics backgrounds, even most of them would not be interested.
BTW, you have no right whatsoever to comment on my behavior. You have been a total A** in this thread. You weren't always like this to me in the past, but you sure have been lately. If you continue to be this way, you will certainly get no more replies from me.
Peace,

Try 25 years of it and see how you feel. One day, one week and you're upset? How about 9,125 DAYS?!!I edited out the parenthetical. It wasn't necessary and I worded it poorly.

You must play on really slow and sticky cloth that never gets cleaned, in a humid environment with filthy balls, where nobody knows how to draw the ball!
With a good draw stroke on fast, slick, and clean cloth, and with new and clean balls, the reactions in the videos are quite normal, if not mediocre. Haven't you ever seen some of Corey's famous draw shots. If not, I can provide some links.
Never thought I'd be giving accolades to Lou for a post but when he gets one right...Why?
Because I dare disagree with the Great Dr Dave based upon my own personal experience? You have conducted yourself in this thread like an authoritarian snot-nosed ivory tower academic, repeatedly demeaning others attempting to understand your “scientific”mumbo jumbo.
Now you have the balls to threaten me with not responding?! (That I’m going to even care.) That’s beyond pathetic and far below what I’d expect from someone like you. I guess a college degree ain’t what it used to.

Here are excerpts from that review of the Stinger A1 in early 2007 InsidePOOL Magazine:I wasn’t. I did a hands-on review for Inside Pool on the Stinger Break cue when it first was built (mid 2000’s, built by Jericho). My league teammate thought the tip was so hard that he wouldn’t be able to do anything except hit center ball. I handed the cue to him to try a draw shot. The cueball zinged backwards like he’s never seen before. He then started doing full table length power draw shots. He couldn’t believe it. Harder tip sounds like crap, but had more hit efficiency.
I need to pull the InsidePOOL Magazine review up from my archives to see if I mentioned my teammate drawing with the cue.
