Dwell time seems to be a hot topic among TT players but honestly I bet NO ONE really anything about it. All they know is the myths perpetuated by the TT forums.
Let me start by saying dwell time can be infinite. If your paddle is horizontal to the ground and you place a ball on it it will stay there indefinitely until you tilt the paddle. The dwell time is infinite. This is an extreme case but it is a simple case. If the ball is stationary that means there is no net force acting on it. The force of the sponge pushing up on the ball is equal to force downwards due to gravity. This is a fundamental concept that the stupid physics PhDs and moderators on other forums don't seem to be able to grasp.
You can see that in this case having infinite dwell time really doesn't help with generating speed or spin.
If anybody wants to learn more I will explain more and try to keep it simple.
