What school teacher? I am very skeptical of school teachers. They rarely have real world experience. They teach what they have been taught and often get it wrong. The Magnus effect does not cause wobble. The Magnus effect makes the ball curve to the right or left depending on the spin. The...

Are low spin balls a loop when they drop mostly due to gravity instead of the Magus effect?

I think igorponger has a point. The sponge and top sheet should be certified together. Long ago, Pathfinderpro was trying to evaluate the effect of sponge thickness on the bounce/return of the ball. The problem is that he chose Chinese rubbers where the sponges where different from one...

I know that. Tensor is also a mathematical term. How much tension? So what hold the rubber and top sheet in tension? Show me a formula for the speed after impact that depends on tension. You can't. Tensor is just a name. The only time the top sheet is in tension is when it is putting spin on...

Yes, it like lodro and others saying a ball has weight instead of energy. Yes a ball has a mass of 2.7 gm it is also has translational and rotational energy, not power. Stupid people have try to de-rail my posts. Long ago I tried to explain dwell time. A person tried to tell me I was wrong...

Yes, the speed and spin of the incoming ball AND the stroke are assumed to be the same. However, why do you want to hit a ball with a high arc? That would mean it will bounce high too. This means one must change the stroke and attitude of the paddle to keep the trajectory low over the net...

What kind of engineer? As an engineer you should know there is a limit to the coefficient of restitution. COR.. There is a limit on what the coefficient of restitution can be. What improves is the marketing to all the suckers. Igorponger is right about testing the balls by dropping them on...

Energy is the correct word for it. People generate power, not equipment and balls have rotational and translational energy. TT balls have a mass of about 2.7 grams. There for formulas for the rotational and translational energy of a ball. The mass of the ball is fixed at about 2.7 grams.

The problem with the video is that he is talking about friction first being wrong. He is talking as if it is an all or nothing thing. It isn't. There is an optimal spin to speed ratio for every shot and that depends on the circumstances. Sometimes I must hit the ball from below the net or...

You said that just to show your ignorance and get a rise out of me. Balls have energy and their weight is only about 2.7 gm and that doesn't change. Energy can be rotational as well as translational. I suppose that you, or any of the people that liked your comment, have never had a good play...

There are wood glues. Don't use the glues you use to attach rubbers. It also works best if the rubbers are removed so the wood and the vice make contact. Now you know the wood is pressed flat.

I have damaged my paddles even worse. Yes, I put clue in the crack and then put the paddle in a vice.

There was a very old Chinese player that came to the Portland Table Tennis Club. The people that knew him called him 'The Master'. The better players would line up to play him and he beat them all. He played like HZW only not as mobile at his old age. It was an eye opener how c-pen blocking...

I like the simplicity of HZW's style. I like his earlier matches where placement is everything. and his serves set up the next shot

I have played with super anti, best anti, anti power, megablock and buffalo. The first 3 are japanese antis and they do have some friction. Super Anti is probably the slickest of of the Japanese antis. Megablock and Buffalo are Gernem almost fricitonless antis. Their top sheets are...

@Gozo, you posted a recent video where you hit the ball into the net. Your previous stroke was a top spin and it came back with back spin which you hit into the net. This is a no brainer. I play with LP 0X in push blocker mode at time. My practice partners have played against me in push...

I don't believe that is exactly what I have said but I agree. there is NO SPIN A LP can make that an inverted cannot. It just takes different strokes. Also, I saw the video where Gozo tried to loop two balls in a row against LP and the second ball went into the net. All I can say is well duh...

An extreme choice would be a Japanese Anti like Yasaka Anti Power or Nittaku Best Anti. They have a little friction but not much. For even less friction then there are the frictionless anti of which there are many.

Very similar. It is based on the likely hood of victory given a point spread. For instance, a difference of 100 USATT rating points means the stronger player will win about 5 out of 6 matches. The USATT table of points one or lost based on the ratings difference is similar to the USCF...

I second the Donic Defplay Senso
