Is maximum topspin overspin?

i think you need a high speed camera to really do this test. if overspin exists, it would be so slight that the naked eye probably wouldn't notice it--and in your video i don't really notice the sand paper moving.

ray romano?

This vid is a waste of time.

Hey man.. can we play for a few bucks? :)

i usually am low and sweep up...

Why dont you become a partner?

Some people think it is necessary to have overspin to get good action on the cue ball. In fact smooth rolling is about the best you can get. Other (more expensive) experiments have shown very slight overspin which will quickly dissipate.

If you have overspin when the cue ball hits the object ball, you can follow through at a straighter angle. It's real hard to get such overspin and it doesn't stay on the cue ball for long.

Is that an OB 1 shaft on your video? What is your opinion on that shaft?

Your jumps are causing the cueball to lose contact with the sandpaper virtually at the point of contact and this combined with the fact that alot of that spin you are trying to impart is lost via the elevation causing a reaction you are not seeking is likely to alter the results of the experiment.

If you watch the way you stroke the cueball at 4:52 especially you can see that the cueball is loosing contact with the table and the overspin if it exists is most definately not going to impart.
