Cue Tip Contact Myth-Busting Truths in Super Slow Motion

Except...

Freddie's post comes after this thread is filled with detailed explanations repeated over and over (including by Freddie) of what pvc lou and others can't seem to grasp. Where's the CTE thread that even comes close to that?

It’s funny how consumed you are with CTE lmao. 25 years of not understanding CTE and you just keep bringing it up every single chance you get. What a life. You going to put CTE on your gravestone?
 
It’s so nice of you guys to keep CTE alive on the main forum. Thank you very much.

In the immortal words of Smorg: “stinky bait.”

You guys just keep on keeping on with your suicide by mod. You’re doing fine right about now by me — you boys keep the pedal to the metal ; -)

Seriously? You’ve transitioned through :

Softer tips create more spin

to

Tip hardness makes a difference somehow since Dave said to be more delicate with a hard tip vs soft speeds.

to

There is a difference in tip efficiency.




Am I really an engineer? Let’s add you to that other guy who didn’t understand the basic ideal gas law that questioned if I was a mechanical engineer (who actually focused on thermodynamics). He lost on that one as well, and to his credit gave a video of his apology.

I clearly understand mechanical physics. You’ve already insulted two other guys whose careers based on the study physics have been very successful. I guess you insulting me as you did them should make me feel privileged.

Where did you go @Cornerman? I'm trying to help you through the logic step-by-step.

@Patrick Johnson can join us for class, and maybe if you two behave there will be juice boxes at the end...

I'll try to be more explicit since you (and others) don't appear to see the common thread connecting what you consider to be disjoint thoughts aimed at what they call "moving the goalposts" these days.

What is in dispute is "Myth 3" in Doctor Dave's video: "Tip Hardness Effects."

At 3:06, Dr. Dave says: "Some people think that because a soft tip stays in contact longer with the cueball, it can impart more or less spin than a harder tip. But this is not true. For an explanation why see the tip hardness effects resource page linked in the video description."

This claim is made after showing that the measured contact times for a phenolic and a soft-leather tip are 0.8ms and 1.9ms, respectively. A difference of a factor of 2.

Ok. So, double the contact time, and the "imparted spin" in the words of Dr. Dave, are effectively the same. Contact time has no effect.

What does it mean for a thing to have no effect. Let's consider a simple example:

Whether I wear socks to bed has no effect on whether the sun rises tomorrow morning. Therefore, if I wear socks to bed, or I don't, the sun will rise. I won't have to pull one sock off my foot or add an extra sock to the other foot to compensate anything. The sun will rise no matter what.

Now let us return to the question of tip hardness and imparted spin. Dr. Dave said earlier in this thread that to get the same imparted spin with a hard tip, a more delicate stroke is required. Therefore, the hardness of the tip is not independent of the imparted spin.

This is already a lot to digest, Engineer Fred. We can return to the so-called tip-efficiency later, when we sort out this first piece.

Thanking you for keeping CTE alive in the main forum is “ suicide by the mod”. Tough group here. I don’t include you in the group by the way.
 
I don't know why many say using soft tip is bad because you need hit faster speed. I think it is good thing. My experience it is easier to stroke balls little harder than slower. Especially under pressure.
 
Man you guys sure do overthink the game.

None of this stuff really matters. You wanna play high level The only thing you need is to be extremely comfortable with your cue and trust your instincts.
Know the limits of your stroke....that way you know the shots you cannot execute.. everything else is fair game.

As long as your pre-shot is solid and consistent...your gonna make your shots.

Getting better means increasing the limits of your stroke .... attempting shots over and over in practice

to do this you need to shoot with the same cue all the time.

That's pool guys . None of this Tip hardness contact time cue construction...shaft tapers and diameter cue balance. It's what u like and your comfortable with. Sure different cues feel different ..but the only thing that matters is how comfortable u are with it.

.08 seconds or whatever....what does it even matter
 
Hell, i still hear that Meucci's could draw the ball better because the shaft was whippy. Some of these old tales still hang on well after they've been refuted.
Give SRV a Les Paul he's gonna play a little different. Sure it sounds like SRV your sound is in YOUR hands.....

but he's gonna stroke that Les Paul slightly different than his strat...because the guitar will inspire to try a different way.

This is why different cues can seemingly do different things better.

People aren't robots. We have feeling...why try to take that away. If I draw the ball consistently further with a meucci than a viking....well then meucci draws the ball easier and farther than viking. (Weathet the difference is me or not) It's pretty simple really

No PhD needed

Whoa.. Post 475. It's like old times.

In fact I did a couple checks on the date to make sure it WASN'T old times...

Spin-to-speed ratio (apples).

Dr. Dave said earlier in this thread that to get the same imparted spin with a hard tip, a more delicate stroke is required.
RPMs only (oranges).

Therefore, the hardness of the tip is not independent of the imparted spin.
Misunderstanding of cherry-picked statements.

It’s the Way Back Machine. Or a class reunion. Can you convince Ron Shepard to come? I think Steve Hegg’s clone might be here.

Obviously it's not obvious if there is a thread with everyone blabbering about stuff that makes no difference for 24 pages.

people reading AZ and trying to apply it
This is why it's hard to find a game of pool where a guy doesn't take a minute every damn shot.

It's not obvious. Half these guys don't even know who SRV is. And 95 percent probably never touched a guitar. Lol
