...but it's interesting.

Thanks for sharing! Doesn't really say anything to be honest, but shows some relative speeds between types of rubbers and blades. Interesting to note that long pips are significantly slower than hardbat rubbers, even on a much faster carbon blade.

Wish they would have shown a comparison between the Hawk and a real Hock 3-Ply w/ same rubbers (they didn't say what blade that Leyland was on at the beginning) .

It proves that testing is only meaningful when there is only one variable.
I seem to remember people pointing that out to me when I was "testing" my rubbers using my own unique methodology.

The title of the clip is misleading because it is not really about Leyland cf with other rubbers. It's about Leyland plus blade against other rubbers on different blades. Even where Dr Evil is used on the same make of blade, I'm assuming that it wasn't the same blade. I would be much, much more interested to see what happened if each of the rubbers was used on the same racket.

It proves that table tennis robots don't always give the same ball in the same spot

"All your spin are belong to us!"

In some cases that bat was not clamped exactly the same and therfor the ball went a different direction (so some were a bit pointless)
If the same rubbers were used on a selection of the same blades, then looking at the height may be usefull or knowing the influence of the backhand rubber may have show'n us something of interest as well

BUT in real life strokeplay is what determines a rubbers capabilities and matching rubbers with the right blade and users suitability

It is a test similar to the tests we (the USATT Hardbat Advisory Committee) conduct to determine if a rubber is suitable for hardbat play. The difference is for official test purposes we use the same blade for all the tests.

The length the ball travels = speed of rubber.

The bounce of the ball = spin of rubber.

The new rubber is measured against the control rubber. If it is faster and spinnier than the control rubber then the candidate fails.

CHEERS!

Wow Alberto, when/how did you get on the Hardbat Advisory Committee?

Abdulmuhsee: It says tim wright ultralight for the blue leyland blade

Gnopgnipster: Do you test at one speed or different speeds / spins? Do you test top and chop? When you say bounce do you mean height, higher failing?

Huh.. didn't even occur to me that was a blade; thought it was the name of the person performing the tests or something.

This is the third year I am on the Committee. I put in for it and got in. All the committees are listed on the USATT website.

The test was done on one speed and spin (same for all). The machine setting is only for topspin. Bounce means height the ball travels. You take the average distance, and average height.

Well what do you know, you're the chairman of the hardbat committee while Al Papp and Trevor Runyan aren't even on it anymore. I'm way behind.

This was my video. It was made in a response to an English player who was claiming that Dr. Evil reverses spin. This player also seems to think that Andro Classic is a better and more classic rubber and that Dr. Evil is an abomination for classic play. I disagree. So the first three tests are the core tests and the reason for the test to begin with. The rest was just tossed in for grins and to provide comparisons to a few other standard racket/rubber combos. I Dr. Evil on a number of blades to as an attempt to provide a better relative base of comparison. If I had my 'druthers, I'd have used the same blade for all tests.

The same blade was not used due to the issues of removing the old Blue Leyland rubber. The best I could do is to use another blade that was the same model. The Dr. Evil and Andro Classic rubber were on the same exact blade which was the same model blade used with the Leyland rubber. I used Dr. Evil on a variety of other blades as a point of reference for some of the other comparisons.

It is true that the blade was not positioned exactly the same in all tests. But it was adjusted to be fairly precisely vertical before each test. I used a bubble level against the face of the racket to ensure verticality.

What the main test shows is that the ball comes off of the Dr. Evil very much like it comes off of the somewhat aged but still soft Leyland. Look at the height of the ball and how deeply it lands. If anything, the Dr. Evil was a bit more lively than the Leyland. But it is easy to imagine how brand new Leyland might be more lively than either of the two rubbers I tested.

It also shows a distinct difference with how the ball comes off of Andro Classic. The trajectory is much lower. The lowest of any of the rubbers tested, other than the Feint OX. Compare the Andro Classic trajectory to the Feint OX trajectory. Andro Classic is certainly not a long pip rubber, but it leans that direction in how it plays.

Note also how much higher 802-1 OX goes. The same goes for 799. It is no wonder these were not approved for hardbat by the USATT Hardbat Committee.

Sorry for commenting so late. I only recently ran across this thread.

Great illustration of the different effect from the rubbers!
