A revamp of the system to fix a discrepancy that happens every blue moon with minimal consequences could be an expensive overkill. Rating inflation is a problem but what kind of inflation are we talking about if it seldom happens? It's just an annoyance.
David Marcus' Rating Central endeavor could be the solution but mysterious ping pong politics always prevented his system to shine.
The reason why this is a big problem was explained in the MyTableTennisTT.net forum to MyTT Admin StillTT more than 2 tears ago
But since MyTT has a policy of punishing posters simply based on who they are, StillTT (or anothe MyTT moderator) deleted that posting/

Yeah it kinda is. It's a matter of principle. Some guys work their butts off 10,15,20 years to reach 2000 then some crummy low level player like this waltzes in,plays one tourny and is erroneously bestowed with a 2150 rating. That aint right. USATT needs to fix that loophole.
Well said tomkat22

All this was exaplined to USATT committee members 2 years ago.

It is not just few cases
There are scores of cases

It was explained 2 years ago as to how the whole rating system can be skewed due to this serious flaw in the system

USATT continues to ignore it

As I understand it was already done 2 years go.
All member sof all USATT committees were contacted as were presidents of most TT clubs in USA
tomkat22 wrote: Maybe if an unrated player loses all his matches in his first tourny he gets a default rating 500 points lower than the lowest rated player who beat him in that tourny.
500 points is still not good enough.
This is what actually happend un US Opens & US Nationals

A player can play Kou Li & Kanak Jha in the US Open and get a 2300 rating based on your 500 point rule

As was pointed out 2 years ago, the best solution is to wait till a player has ideally 5 wins or at least 2 or 3 wins in USATT tournaments or USATT league

You are correct. It is beyond naive. Because you have not understood the very purpose of a rating system.
Yes it is one of the purposes of the rating system tp prevent players from entering a lower rated event but that does not mean they should be "awarded" a Master level rating to start with just for participating LOL

groupoid wrote:It sounds kind of naive, but my understanding is that the main goal of the rating is to prevent players that are too strong to enter events such as U1000 or U2000. In the case described above (all losses to high rated players, no wins), USATT has three choices:

1) Assign a high rating as they do now.
HELLO !!! Do you even understand the very purpose of a rating system & how various ratings interact ?
OMG you just want to "award" a high rating for a player for just participating ?
Seriously ?
groupoid wrote: 2) Assign some kind of base rating (say, 1000), or perhaps assume that every player is rated 1000 to begin with (perhaps with some exceptions for players already rated in another country or internationally).
Do you even understand even how impressive it is to earn even a 1000 rating in USATT ? OMG

groupoid wrote: 3) Do not assign any rating until there is non-trivial win/loss data.
This is the right solution proposed two years ago in this forum.
Wait for the player to get a certain minimu number of wins like 2 or 3 (ideally 5)
This would encourage participation as well
Case 3) is just postponing the problem to the future.
How is it postponing the problem if you require a player to have a minimum number of wins in tournaments before getting a rating assigned to them ?
If you want participation such a method will encourage participation LOL
groupoid wrote: The only problem of Case 1) I can see is that it can hurt the ego of some people.
Again you want to award someone a ridiculously high rating just for participating. But as TomCat22 points out & was pointed out 2 years ago , do you know how many players work so hard to reach a rating of say 1400 or 1700 or 2000 or 2200 etc. It i sis such an insult to those players
groupoid wrote: Plus, one can get free points.
Free points for what ? Just participating ?
Again you don't seem to understand the very purpose of the rating system

Dear Groupoid,
I think you have confused the USATT's new fake ranking system with old rating systen.
The new ranking systemn is the fake system designed to award players a higher ranking kust for participating.
It is pure fake & pretentious & the sooner the USATT get s rid of it the bette roff they are.

USATT rating system is sacred and holy for most players (who strive hard to reach a higher rating)
You want to make a mockery of the whole rating system

You feel thi sway because you have not understoof the very purpose of ratings & how they work
Worse you or StillTT have not understood how it can potentially severely destabilize the the entire rating system.
This was explained two years ago in another topic
