"This rubber is not correct!"

[ZFT]

You can provide the example you have in mind. Your list is inverted player faulted for rubber thickness and VOCs. If someone got faulted for friction test, you can share. I don't have to substantiate it, you can provide one example if you know of it.

So let me understand this:

You want others to prove you right, even though you got nothing to substantiate your claims?

Make it make sense.

Levenko responded on reddit and says there was no racquet control. The umpire apologized to him after the match since they are friends.

What exactly does "no racquet control" mean? What exactly did the ump apologize for? If the ump is friends with a player, he should not officiate that match.

If you watch the beginning of the match, you can see the match official brings both players rackets in envelopes in the usual way, so both players submitted their rackets for pre match inspection.

Where is the published procedure for friction testing?

Once again, the ITTF T9 document has no friction test. The officials would check if the rubber is on the LARC and look for broken pips.

You can't complain about not doing a non sanctioned friction test. (well you can if you are Igor, might as well add the oily booster detector to testing)

No. I actually posted that the test procedures written by the ITTF have zero tests listed for rubber friction and I wasn't the one who claimed that there was a test for rubber friction being used by the ITTF. It is up to the person who claims that to substantiate it. Hint: read prior posts and figure out who made that claim.

Say....@Igor is really quiet on this. I would have thought he would relish and embellish on such a topic.

Then the real point is that claiming that pips rubbers are illegal if they don't have a certain friction limit is useless because there is no test for it.

so how do they test before going on LARC then
according to your sources, there is no tests done?

I know that there is friction tests for LARC, I would believe the same friction test is done at racket controls.
you making it sound like there is no friction tests what so ever, which I will be very surprised if there is none - since CTTA would be the number 1 MA to fight against that.

however, with ITTF track record of enforcing rules that are not policable does happen often.

Exactly and since I posted the tests that ITTF does at racket controls, I will wait for your evidence that they test for friction. Absent that, I will assume they don't. I am open to evidence that they do. I just haven't seen any. When you have your evidence that they do, please provide it. Right now, you are providing evidence from what is done/tested when rubbers are manufactured or checked for LARC which is not the same as what is done for racket control.

I did some digging,

1, 2 and 6 will be applicable for pimples, with 1 being the only part where frictionless will likely fall fall under.
The whole documentation on that part is very vague.

any ways, I have sent my query in and will hear what higher experts has to say.

don't boost (I mean burst) his bubble

 

[NetProphet]

It's clearly he hit Pistej

Yeah, he walked into him, no question.
My point is that Pistej deserved it.
They are men, not sterilised clones and the initial aggression was from Pistej kicking the table 😂
If you push and push and look for a reaction then quite often, you'll get one.
It's not the one Pistej wanted as he'd have preferred to break Levenkos concentration.
Only issue I have is that Levenko blamed Pistej for the contact rather than owning it up to it!

I swear. This is going to become a table tennis meme.

i just found something uplifting. Somebody beating Naplokov even though that dude would have lost against 90% of the higher rated players that Naplokov slayed recently.

This is Francesco Maragioglio from TTC Oggersheim (Germany). He is above 40 already and plays short pips on his backhand.

While before this game one could have opined that Naplokov simply does know better how to work with pips out and does understand how it affects the ball rotation, we do clearly see that he is as clueless if the opponent takes his "unpredictable" spin and returns it with short pips. The amount of times Naplokov cluelessly pushes the ball into the net or tries his backhand smash also landing in the net shows how he is as clueless against pips-out as most. To put it hyperbolically: He is not better at understanding what short pips do to a ball and what spin they generate, but he only benefitted from him basically playing every ball back with the seemingly randomness of his pips out, so the opponent had more balls to struggle with. Now there comes a player that only uses pips-out on one side and he crumbles and looks stupid like the others that looked stupid against Naplokov.

Here i found another match where Naplokov was beaten by Marco Stefanidis (who does not play anything other than inverted) and i think Marco's tactics with looping first with spin and the second loop killing would have easily granted him the win. His game is very exhausting and it seems like Marco did not have the stamina to pull that through unfortunately and so it was quite close.

why not?

how good these players usually are?

 

[Tony's Table Tennis]

okay,
i'm comfortable to say, there is nothing done to regulate friction-less long pips during racket control.
only extra long stare at the rubber and that is about it.

i have check with coaches of players, and players, as well as top ranked players that take parts in olympics/world champ/smashes etc.

I have yet to receive feedback from my sources in WTT, but the players feedback has landed solid conclusion. lol

so what is done is to check everything - based on inverted.
including checking the likes of LARC and spot any "irregularities with the naked eye".
some long stares did occur, but play on.

so, yeah, technically they do check pips too, but in the same time making rules that can't enforce continues.

As an LP player myself, I just need to rub the pips with the palm of my hand to check for grip. I know it's not scientific whatsoever, but if you've touched enough legal LP's, you know what friction vs frictionless feels like.
But, who knows, the player may be just slightly altering the pips, not enough to really notice, but enough for an advantage. We definitely need some sort of instrument that could measure it, though.

Levenko just didn't know what to do.

yep any LP players will know this, the palm test is the same as ball rubbing test and the Yinhe device

I am told if the racket control staff feels it has been tampered with, then they will stare long at it.
but so far, didn't get infraction.

and since the yinhe devices is used domestically, i wonder why it isn't approved for ITTF racket control - maybe because igor was involved with the fake submission?

The LARC approval test is a dynamic friction test. Mfr sends rubber to ITTF, which sends the rubber to a third party lab where rubber is tested in lab conditions with controlled temp and humidity. The machines that do this cost thousands of dollars.

Igor's plastic contraption measures static friction, which is not the correct test.

There are many variables to try to accurately measure friction at a playing hall. Friction will change with temp/humidity. Is the rubber tested in a controlled environment? Hitting balls changes friction. How does powder from new balls affect friction? Does your rubber pass in the morning but fail a few hours later? Are you going to require that players clean their rubber?
