Is this the typo: "The longer the contact, the more margin of error you have"? #1

The longer the contact, the more margin of error you have.

Shouldn't it be "The longer the contact, the less margin of error you have?

This is a great article, thanks for the information.

The way I understand it, if you have less time to put the ball where you want, you have to be more precise with angle and speed. Longer dwell time allows some adjustment to work out a trajectory. But, I didn't go through any training, so couldn't be totally wrong.

Ok, the thing you mentioned is right but I think in the context of that paragraph it should be "The longer the contact the less margin of error you have". Because it was being mentioned that: "It is only when the ball and rubber are in contact, you have the opportunity to apply power, spin, and direction" and later it was said: "One way to increase this duration is to approach the incoming ball slowly so that it takes longer time to slow down, and accelerate after contact so that it takes longer time for the ball to catch up in speed. In one swing, it is a quick acceleration." and in between those line it was mentioned that "The longer the contact, the more margin of error you have". I couldn't digest it as I was expecting that the contact point of ball with racket should be increased so better transfer the speed and spin as we need to drive instead of just hitting but it was mentioned opposite.

Is this true? It is interesting. If you haven't gone through training then how do you understand all of these concepts? You are physics related person?

I have read the whole page and everything makes sense. I was wondering if there is any video explaining all this steps? Where did you learned all this? Can you share some link to the resources which helped you understand all these?

I am with you. Can't really find good slow motion videos to understand the dynamics. My school work was all about trajectories, so I am curious about how it works.

I see, is there anything you can share with me about trajectories for table tennis?
