Receiving serve before year 2000

I know that you are an athlete before the year 2000 representing Australia, so can you tell me how you watch the flight of the ball more closely and adapted? So in future, if I did not see the contact well, I can watch the flight of the ball.

This comes with experience.  When you are forced to watch the ball in flight you start to pick up subtle differences. The backspin will float more, the topspin will dip more, the sidespin will curve.

Sorry, but I don't know what you mean by "The backspin will float more, the topspin will dip more"

Backspin fights gravity force,so it will fall slightly slower.

Topspin cooperates with gravity,so it will fall a bit faster.

Thanks for the information, D K

It is the only way for me to differ the spins.
My eyes are too bad to watch opponent's bat at it speed.

But be careful,my experience is that a sidespin weakens both effects.
That means that it is more difficult to differ backspin from topspin if they are combined with sidespin.

Thanks alot for the information. Why don't you wear a glasses so that you can see clearly at the opponent's bat?

I wear a glasses....but this works only with static things...it does not help me with seeing fast movement.

If you want to discuss this please write me on "great-polis@seznam.cz",I do not want to spam PingSkills answers with this again.
