Rating floor
I think this is a great idea, although I appear to be missing something. The floor is established by
'simply subtracting 200 from the player's highest rating, and then rounding down to the nearest
hundred'. Therefore, a highest rating of 1770 should have a floor of 1500 (1770 - 200 = 1550,
rounded down to 1500) yet my rating floor is showing at 1400.

Also, 'Your rating can never fall below your rating floor'. I'm assuming this is not taking into
account an extended period of inferior play? ' '

Good point on the first one...
my rating floor is 1300, when it ought to be 1400 (1625 - 200 = 1425)

Perhaps that's easily fixable, but to be honest I'm not that bothered right now - I doubt I'm gonna be dropping that low   And with yours, it ought to be 1600 [1570 rounds up to that]

I Guess
It is taking your current rating, not your best rating.
I think it said in the message that it wouldn't be applied retrospectively.
So as your rating goes up so does your rating floor.

I think you've hit it. Working from current ratings seems to be the answer.

Checked mine ...
and it seems right. 1848 - 200 = 1648 Rounded Down =1600 and that is what is shown as my floor on my profile.

x-machine Note that it always Rounds DOWN to the next even hundred ... never up even if that is closer. So 1899 still becomes 1699 rounded Down to 1600  

I am happy GK decided to start with -200 rather then -300 however, as was initially stated. Or some might have Rounded Down to near a 400 pt difference, which in Elo terms would have meant that their current self could never have beaten their former self in a game~! OR at least less than 2% of the time. lol

Only unhandy thing I see with this is that track has to be kept of TWO highest ratings - one all-time, the other since-17-Nov-2010

Yes, as mentioned in the announcement, the rating floor isn't retroactive, so it doesn't affect/protect any past rating changes, nor takes into account any higher ratings in the past. Basically, it just takes your rating from yesterday and starts tracking it going forward only.

heinzkat, we simply check if the rating floor needs to be adjusted upwardly (never lowered of course) after each game is finished, so we don't really need to keep a separate "highest rating since 17-Nov-2010".

No matter how many games in a row you lose, your rating can never fall below the floor. That's what the floor is for.

rating floor
In the long run this should inflate ratings.

I thought the rating floor idea would only apply in case of timeouts - the idea being the rating floor is now there to prevent players with loads of timeouts from falling to quite lowish levels ...

So, *every* game result which has not ended in timeout from my side, would still alter the floor value accordingly.
However, if I timeout a hundred games in a row, then yes, those losses should not bring my rating under the current rating floor.

But if you lose a hundred games in a row via checkmate, then yes, your rating floor should drop according to your rating! Isn't this so?

The USCF established a rating floor for two reasons I'm aware of: 1) To combat overall rating deflation, and 2) to prevent players from purposely dropping their rating to get more favorable tournament pairings, and hence win more prize money.

Rating deflation is a big problem with OTB play, since when players retire or die they take most of their rating points with them to the grave. Here at GK, however, when a player expires he often returns most of his rating points back to the community via timeouts.

As far as players purposely dropping their rating here at GK, since there's no money involved there isn't much to gain (other than looking stupid).

Yes,
The USCF rating floor is important,even in corresp.games.There are all kinds of USCF corresp prize tourneys including the 7 player section Victor Palciauskas where the top winner receives $130.00.Other corresp sections are,for instance,the Electronic and Golden Knights tourneys where prizes are hundreds of dollars for not even being first place and a thousand dollars for first place.
Can you imagine no rating floor in these circumstances,especially the Victor tourney with only a $25.00 entry fee?Some players would definitely drop their rating to win a couple of those,especially around the holidays!So,the rating system is in place for a good reason and goes far beyond just OTB games!

Does anyone really expect to drop 200-299 points due to inferior play? Can anyone find a period in their graph that represents such a drop due to inferior play? I'm 1840 right now, if I drop to 1640 due to inferior play I would expect to dominate my new rating range. Of course I still lose to people of this rating, but not often. I just don't think there's a great many people who get worse at chess the older they get.

I guess it protects people from losing their rating as they go senile. I'll be laughing when I'm a crazy 96-year-old who's playing chess like a 1100 rated player with an invincible rating of 1600 or whatever.

Tugger ...
That is indeed a benefit of the Rating Floor ... as we age and become senile, we become very beloved with a 1700 or 1900 rating, playing at 777 (my first USCF rating   ) performance level again.

But I think such drops are more common than you realize. I came here 2200 in corr everywhere else, and didnt have the juice left to work up to it again here. Happy to be a purpetual "A" player; tho probably will be done if it ever falls below that, let alone a rating floor.

Besides "senility", whether the normal short-term memory impairment (commonly no more than 10 or 15% loss) there are those with Alzheimers. Or thing like episodal MS that may attack once or twice during a corr game ... just enough for the one or 2 Bad Moves that swing it. (Each "bad Move" above minor inacurracy tends to lower Performance Rating by 1 Class level in corr. ). Or simply physical pain or impairment so distracting it does the same. But if one Loves the game enough, or Chessfriends; they will play on. And good for them. (In USCF they Can ask for a rating adjustment downward, if it has not changed; but after being floored a year or 2 [if they wish to]. I Forget~! Oh well, there you are. LOL

Look up a player like D. Velimirovic , one of the most brilliant tacticians to ever set up a board in the 70's , whose play becomes different in the 90's, and we wonder what the story may be. (If you can learn, please tell me, for I have searched a number of times to find it, fruitlessly. & You especially, sharing the Tactical flare, will want to see his play if you have not, for that is Almost like missing out on Tal, perhaps like missing Bronstein. )

For that matter, what happens to all the Great guitar players that still live, yet do not play? Do they really chose a fade to black, or ...?! I was just thinking, maybe they would like to come over for a game of Chess !?! lol

PS ...
His Life story is also Quite interesting. Nickname, "The Tal of Yugoslavia". Born to a W-Champ of Yugoslavia. His whole name has meaning. Russian I believe: Dragoljub = Dragon. But Google defines NOW in Serbian to be "Nasturtium- A showy ornamental flower" . This sirname is also subject to interpretations;GoogNow: Serbian: Velim="Say" Mir="Peace"

But Russian is(was?!) more like World Dragon or Sky Dragon from my Translator several Years back; or also Peace for Mir. [All in all what a great name for their space station, @ any way: Peace, Sky or World. Tho the Goog Russian shows little to nothing now]

Perhaps fitting to call him Peaceful Tactical Flower of Yugoslavia; but The World Class Dragon playing Russians! !?

floor ratings and tombstones.....
Hmmmm...
I know how all this new rating stuff works,but I was never near my new 2200 rating floor like others....except in the provisional games,and that would have to be one of the first 5 games which still show 1200.By my first provisional 6th game,I was already at 2363 and never dropped after that at any time lower than 2356.Atleast at 2200,however,I can atleast maintain the lowest Master rating(by USCF standards) rather than have dropped a point to Expert level.
So,the trick is not to play too many games at one time(I never do),so if something happens that I end up quitting,losing,timing-out or kicking the bucket,I won't drop more than 50 points or so.I usually do not prefer to play more than 5 or 6 games for quality purposes,and then usually with 2300+,so I will never expect to drop down to 2200,but if I would ever change my "tactics" and play 50 games at one time or a string of players 2200 and below,then,I suppose 2200 is possible!I actually had a mini stroke about 5 years ago(had double vision for about 2 weeks,then,luckily it disappeared).After that,since I take chess seriously,I never want to play more than a small handful of games,incase something happens again.I may never make it to the button to click on a time-out or vacation!

The thing is,though,there is no permanent GK "epitaph".Its my understanding that if you have lost a string of games and then quit,cannot play anymore due to severe illness or die,then after a certain length of time(I think its about a year and a half),your account eventually disappears off of GK permanently,UNLESS you atleast click on to your account once in a while!
I'm not so sure that you would be able to reactivate your same rating account after a year and a half of zero activity,not even clicking on to your account.

I disagree with this,atleast in part.Why?Because I paid for a "life"membership.To me,thats like buying a gravesite and tombstone ahead of time!And no one should kick over a tombstone!So,my "tombstone profile" should remain on the GK "site"for atleast 100 years like other "real"graves,even if i'm NOT around to play or click on to anything!(Or atleast place it in a deceased side file somewhere to be "viewed" by others!)Instead of smiley faces,there should be flowers you can paste aside of the deceased GK players!Ha,ha!

tactical_abyss
21-Nov-10, 17:28

I have all kinds of ideas!But no one usually takes me seriously,or really cares!
Add a disco strobe light by my name too!Ha,ha!
On a more serious note however,,I am a life member of the USCF for over 20 years now.Even if I remain completely inactive for years or decades...no game play,no anything,I still maintain an "active"status and can enter any US Open or corresp event at a whim,whenever I choose without "reactivating"my life card or standing,rating ect.And I get that Chess Life Magazine both online and sent to me in the mail forever.When I pass away,my brother will get the magazine till they catch on,probably until the USCF realizes that I could not be 130 years old!

Just a quick question about the rating floor.
On GK, will the presently established rating floor never change for a player?
For example,mine is 2200.So lets say I reach 2600 rating one day,(theoretically).Will my rating floor still remain at 2200 from now till infinity,without change?Or should it fluctuate up alittle with rating increase?

The rating floor rises with your rating. If you get to 2600 your floor would rise to 2400.

Garos
That's how it sounds to me too. Tho I have a slight wonder if it is 2600 for sure or 2601 ?! I believe it Should be 2600, but can't confirm it ... Has anyone just made an even 100 pt level and can tell me if your Floor then increased to -200 of that immediately? Just curious, but not so much as to ask GK

That was my experience. My floor was first posted at 1400, then when I reached 1700 exactly a
few days ago it rose to 1500.
baronderkilt

Garos, TY~!
I see that now too ... after seeing the Rating notice from GK and the way it is written. 200 subtracted then round down to the nearest hundred. So if it is already On a 100 number seems no round down is then needed. But it is good to hear that the programming works in accordance with the written intent. Thank you.

BTW, here is the notice. You probably all got it ... but may as well preserve it for posterity within this thread, eh> ? And so . . .
* * * * * * * * * * * * *

"Rating system changes: We've made a couple of small, but important changes to the rating system, that won't affect the vast majority of players in any way, but definitely might help some of you in the future.

We've added rating floors (similar to USCF). To calculate one's rating floor, you simply subtract 200 from the player's highest rating, and then round down to the nearest hundred (excluding the first 20 games, when the player's rating hasn't been established yet). Your rating can never fall below your rating floor. The idea behind it is that if you time-out in a lot of games due to some unforeseen circumstances (and the automatic emergency postponement isn't enough to save you), your rating won't drop too much. And more importantly, when you do hopefully get back to playing chess again, you won't have to play hundreds of games just to break even, and your opponents won't be unpleasantly surprised when your playing skills don't match your temporarily low rating.

Please note that the rating floor isn't retroactive — which means it only takes effect today, and starts tracking and protecting your rating going forward only. You can see your current rating floor on your stats/profile page.

Also, we've changed how the short games (games that end in 2 or fewer moves) affect players' ratings. Previously, they did not affect the winner's rating only, and now they won't affect the losing player's rating either. Same idea as with the rating floor. Most of time the short games happen due to new games being automatically started in tournaments/mini-tournaments/etc. and players not being ready for them and subsequently timing out and losing a number of games that effectively didn't actually happen. Please note that short games will still affect the tournament/mini-tournament/etc. results, and only the player's rating will not be affected.

We hope you'll find these two changes helpful. And as always, thank you for choosing GameKnot as your premier chess battlefield! "

I dont like the rating floor
Well I am sure there are many situations the rating floor is a nice feature. And I am also sure many paople like the idea to have this safety line.

But I for myself believe it affects my playing style. It makes points more inflating I think and I dont like the idea not to be penalyzed if I really play many many bad games.
I guess not many of you would agree with me but I would appreciate an OPT-OUT clause for the rating floor.

I clearly see the GK rating floor forumula.I can't totally agree with it 100% however.
I truly believe that if a player is at 2398 or 2399 ,it should be rounded UP just one or two points THEN down 200 points.Not down 200 points plus the minus 98 or 99 points to equal 2100 in this case.Thats alot of minus points...like 299 points!I believe a player that close to 2400,for example,should have a rating floor of 2200,not 2100.
Where would I draw the line?Just at 98 or 99,not 97 or below.But thats just my thought.
ganstaman
22-Nov-10, 21:55

TA: Why draw the line at 98 or 99 instead of 100? You have to put it somewhere, and the even 100 is just less confusing.
levellerlevvie
23-Nov-10, 02:36

Why going up with 100 at once?
You wouldn't have as much difference if you would go up with 25 or even 50 ... Then there wouldn't be this discussions about rounding
