Its always interesting to me to see a teams initial rank position compared to how they finish to see which team(s) did better/worse than their rank at the start ? Is there a place to see that ?
OLYMPIAD - FINAL Standings - Men's Section
Reb - I don't think so. I mean you can look at the initial RatAvg's and then go from there..old on a second, lemme look... (Insert Jeopardy music here)
go here: http://ugra-chess.com/standings.php
It shows you their originally seeded number with of course, the postions that they finished in

I was really hoping for a Russian Gold medal. Perhaps if Svidler won his game on board 3, I might be celebrating instead of being mopey. Since I read that Ukraine and Israel agreed to draws with 90 minutes, thoughts couldn't stop entering my head of a conspiracy of stopping the powerhouse Russians from winning shiny gold. Hmmm, I might have to bring this up at the UN and email Putin.

The Ukranian conspiracy is more than counter balanced by the Russian conspiracy of allowing them 5 teams !! 
ChessMarksTheSpot, thanks for your journalistic efforts on the Olympiad! The majority of my colleagues are Ukrainian,Israeli orHungarian so it should make for a peaceful Monday :-)

Thanks ! So, according to this, among the top ten finishers the biggest surprises were Spain and Israel , both finishing 8 places higher than their initial rank ! Now I will look to see if any teams finished more than 8 places higher than their start rank.......
Reb - I guess so, but, being Russian, I don't look at it that way LOL 
Nick - thanks. I tried. I really wish though I did the whole event, and not just four days of it. I had a few problems I had to deal with in the middle and was stressed out about things, but, I wanted to do the last round for everyone, even though it is the internet age and information is rampant and my help was generally not needed. But I feel kinda better now that I did this

Haha, true!
Btw, does anyone know what the Rc and Rp columns on the official site mean ? They appear to be ratings assessments but not sure of the difference
Yeah a few teams exceeded their rating averages and finished better, while others just sucked dirt. India to me would've been a lot better with Anand, possibly Top 5, but definitely Top 10 overall.
Btw, does anyone know what the Rc and Rp columns on the official site mean ? They appear to be ratings assessments but not sure of the difference
I've been wondering that myself. Anyone have an idea about this?
Nick - about those two columns:
What does Rc in the tournament table mean?
Rc is the rating average of your opponents.
What does Rp in the tournament table mean?
Rp is the rating performance. Read our section on
rating calculations.
Rating Calculations
The rating scheme used by PlayChess is based upon the rating schemes used by many other organisations (
FIDE,
ICCF,
IECG).
The application - and even more the deduction - of the rating scheme requires a lot of mathematics. But don't worry: as a player you don't need to understand this scheme - PlayChess does all the math automatically for you.
The following "mathematical treatise" is given here just to
- demonstrate that there is no hidden magic in the rating calculation
- enable the mathematicians to check our numbers
- prove how extremely clever we are ... :-))
Rating Scheme for Dummies
If you are just a humble human being, not a god of math, here are the essential ideas of the rating system:
- A rating number measures the strength of a player.
The higher the number the stronger the player. - If two players of same strength (say rating 1000) play against each other,
their rating performance will be as follows:- The game is drawn (½-½)
The rating performance of both players is 1000,
because they played like expected. - Player A wins (1-0)
The rating performance of player A is 1400 (+400 points).
The rating performance of player B is 600 (-400 points).
- The game is drawn (½-½)
- The future ratings of both players will be calculated from the rating performance of the single game played AND from the rating they had prior to the game.
In the example above (1-0), player A had played 4 games before, and player b had played 1 game before. The new ratings of the players are calculated as follows:
Player A: New rating R = (4 × 1000 + 1400) / 5 = 1080
Player B: New rating R = (1 × 1000 + 600) / 2 = 800 - If you win or draw against a stronger opponent (higher rating), your own rating will rise even stronger.
- If you lose or draw against a weaker opponent (lower rating), your own rating will drop even stronger.
The ratings of experienced players (more than 10 games) are calculated by a more complicated formula. There, the simple "arithmetic mean" formula above is not sufficient, because the rating of these players would change VERY slowly (imagine players with more than 100 games!).
The Complete Rating Scheme
Principle. The rating scheme is a numerical scheme, in which percentage results can be exchanged into rating differences and rating differences into percentage performance probabilities. The basis of the scheme is the normal probability distribution.
Provisional and Established Ratings. A player has an established rating, if he/she has finished at least 10 games, otherwise his/her rating is called provisional.
Cut Off. To keep the influence of largely different ratings small for the preliminary (and established) ratings, a rating cut-off is used. Anytime the difference is larger than 400 points, the opponents rating is treated as being 400 points higher/lower than the players rating.
The performance probability is calculated by the formula
D is the difference of the ratings of the two players.
The expected rating changes based on the percentage result is given by
p is the percentage result of the player
and D(0) = -800 and D(1)= 800
The percentage result is calculated by
W is the number of wins
D is the number of draws
N is the number of finished games
For the calculation of the ratings, the opponents "Tournament Entry Ratings", which are valid on the day of the rating run, are used.
Calculation of Established Ratings
For each finished game the rating change is calculated by
W True game result (win 1, draw 1/2)
We Expected result
k Development coefficient
The expected result We is calculated using formula (1) with the rating difference of the two opponents. The development coefficient is a stabilisation factor and is given by
| r = 10 | if Ro >= 2400 | |
| r = 70-Ro/40 | if 2000 < Ro < 2400 | |
| r = 20 | if Ro<= 2000 | |
| p = 1 | if Pn >=80 | |
| P = 1.4-Pn/200 | if 30 < Pn < 80 | |
| P = 1.25 | if 15 < Pn <= 30 | |
| P = 1.5 | if Pn <= 15 | |
| Ro | is the Rating from the previous rating list | |
| Pn | is the number of all rated games upto the previous rating list. |
The next rating is calculated by
Ro old rating of the player
SUM(dR) Sum of all rating changes as calculated in (4) for each game
Calculation of Provisional Ratings
The Provisional Rating is calculated by
Rc Average of the opponents tournament entry ratings
D(p) Expected rating change based on (2)
F A Correction factor given by F = -2*p*p + 2*p + 0.5
Denmark finished 25 places higher than their start rank and looks like its gonna be hard to beat that and I noticed that Bulgaria finished more than 25 places lower than their start rank..... very bad Olympiad for the Bulgarians..... but a very good one for Denmark !
I think Rp = rating performance ? I am not sure though and have no idea what Rc is.....
There were only 2 teams ranked in the top ten that didnt finish in the top 10 : Azerbaijan and Bulgaria ...... they were replaced by Israel and Spain ! Bulgaria had a forgettable Olympiad to be sure......
Reb - I'm not really that shocked about Israel's placement in the Olympiad. They had a solid team and played all their matches pretty well. Spain shocked me, as well as the U.S. team, they entered 9th and left 9th, I figured possibly they might go higher than that with the team they fielded.
Armenia was a little disappointing and Mags showed that he was, in fact, human and capable of getting beaten. Ivanchuk was a machine throughout this entire event, pretty much giving Ukraine gold just on his shoulders. And I still want to enhance my feelings about India and Anand. I don't know if that is going to be mentioned in chess circles in the next week or so, but, him not being there was crucial to that team.

I think among the top 10 finishers Spain is the biggest surprise, by far . While Ivanchuk indeed deserves high praise they had another team member that won 6 games while not losing once ! Efimenko ?! I haven't heard this name much. While the Russia 1 's top scorer was Karakin..... who is Ukranian, what if he had also been on the Ukranian team ?!
Sorry, couldnt resist that one !
I dont understand why Anand missed leading the Indian team either. In 2008 he had the excuse that he had just finished his match with Kramnik , maybe he has some excuse this time too, I dont know. He has been living in Spain for many years and I wonder how much better Spain would have done if Anand joined the team for Spain ?
Reb - you're right about Karjakin. I would shudder to think the results that Ukraine would have if he was playing for them. Probably would've been a lot easier for them and not so close in the standings.
About Anand, this really bothers me a lot. He is the World Champion and ranked #3 in the world behind Topalov. Now I was rooting for Topalov in the WC match in Sofia, despite his cheating image he has on him, but Anand missing this event, hopefully for some serious reason, really, to me, brings a small dark cloud over him. I might be pushing this a little too far, but it just irks me. I do hope though nothing serious happened and it was just about the money as usual.

here we go everyone, from Chessdom.com:
Note: Tiebreak criteria
1. the sum of Sonneborn-Berger points, which are calculated as follows: match points of each opponent, excluding the opponent who scored the lowest number of match points, multiplied by the number of game points achieved against this opponent;
2. by the number of the game points scored;
3. by the sum of the match points of all the teams opponents, excluding the lowest one.
