Show me an equation that shows that tacky rubbers are spinnier.As I can see, you are just imagining things 😏
Do a normal pure backspin serve, which can generate more spin, tacky rubber or non-tacky rubber?
When doing a ghost serve using non tacky rubber, you toss the ball straight up and move the paddle horizontally quickly face up. When the ball touches the rubber the rubber there is no force so there is no friction but eventually the friction builds to the point that the ball grips. The time for the ball to grip takes microseconds, normally.
If the ball is not tossed high enough the ball will not grip as quickly are maybe not at all but if the serves are tossed at legal height the ball should grip quickly.
Tacky rubbers will grip without much mechanical friction and maybe with no "mechanical" friction at all. A tacky rubber may grip even with a low illegal toss.
Take this to the extreme. Put a ball a horizontal non-tacky rubber and try to serve with the paddle horizontal and a horizontal motion. Since there is little downward force, only the weight of the ball, the frictional force is low. The ball will just roll off the paddle as the paddle moves forward.
Try this with a tacky rubber and the ball will move forwards and with some back spin. There will be more spin because now there is the small frictional force and the tacky force applied to the bottom of the ball.
I think this is intuitive. BUT!!!!! That is not what really happens during a serve and the frictional grip or tackiness is not what makes a rubber spinny.
The frictional force is equal to the normal force x coefficient of friction. The normal force increases at the ball penetrates the rubber so the frictional force does too. Also, there is a big difference between static and dynamic friction. Once the angular velocity ball is low relative to the top sheet the friction increases.
When serving with non-tacky rubber, the ball must be tossed high enough so the ball will impact the rubber with enough force so the frictional force will cause the rubber to grip the ball. How high to toss the ball is the trick because if you toss it too high the ball will bounce high but at least it grips quickly. A low toss may not be legal and it may not hit the rubber with enough force to cause enough frictional force to grip.
If the spin was only determined by friction or tackiness then all the rubbers would generate be the same spin since the difference between when the ball grips is very small or none. In this case the surface of the ball would just move with the paddle. What truly makes the rubber spinny is the fact that at contact, the stretches the rubber a little across the face of the rubber and when the rubber snaps back, it adds extra tangential force/speed to the ball causing more spin.
