TT myths that need to be busted.
1. rubbers or blades have power. They don't. You do. Blades and rubbers are inanimate objects that won't move without some outside force. People generate power.
2. rubbers or blades have control. They don't. You do. You control the stroke.
3. SP have a sink ball effect. Well they do but you can duplicate the same effect with inverted rubbers. There is no force or impulse a SP can generate that an inverted rubber cannot.
4. hard rubbers are faster than soft rubbers or the other way around. It is more complicated than that. People talk about how springy a sponge is and that is a good indications of how fast the rubber is but it is really the internal damping. If there are any mechanical engineers here they know about the mass on a spring with a dashpot for damping. No one mentions the damping and damping is important..
5. Thick rubbers are faster than slower rubbers. Rubber doesn't generated energy. It absorbs energy. Given the same stroke a thinner rubber will be faster.
6. LPs generate wobble balls. There is no wobble force generated by a paddle or rubber. LPs do generate a higher percentage of dead balls than inverted but basically there is no force an LP can generate that an inverted rubber cant. Inverted rubbers should be able to generate wobble balls too but there is no wobble force. If a ball appears to wobble it is caused by the ball being moved by air currents or eddies around the opponent. It has nothing to do with the rubber or blade because the paddle has no effect on the ball after it has left the paddle.
7. Dwell time is not long. Dwell time is very short. It is on the order of a millisecond to millisecond and a half. I have high speed videos to prove it.
8. Accelerate through the ball to increase dwell time or hold the ball on the paddle. Yes, it does increase dwell time but on the order of a few micro seconds.
9. Heavier blades are faster all other things being equal. Yes but after the paddle gets to be about 160 gm the increase per gram diminishes rapidly. If a heavier paddle is faster then why not play with a 300 gm paddle.
10. The flooring under the table makes a difference to the bounce. It does but like myth 9 the effect is so small that one couldn't measure it.
11. Rubbers are tensioned. What a joke.
Let the heated discussions begin!!!!
The rest should just sit back and enjoy the thread.
Musicians have their myths too and are gullible.

This is like rating a blade or rubber at 10+++
Izra, did I miss anything?
Feel free to add other myths that I may have missed.
