So you're basing your study plan on a mysterious number so that you can filter out material that's correct for your level? I don't see why you need a number to do that.
Pursue material suitable for and if you find it too rudimentary, move to books recommended for the next rating class.
Rinse and repeat. It isn't too hard. IT doesn't take too long to figure out what's over your head and what isn't.
I don't see a phenomenal jump in the efficiency of your study-time by hunting down this mythical number and THEN filtering the quality of material flowing into your cranium Or better yet, taking a closer look at your lost games and having a strong-er player go over them with you.
My CFC rating used to about On here, my blitz rating fluctuates anywhere between and admittedly on the lower end right now.
Shivsky, thanks for your input and while I can't help but agree with your sentiments I do think there is some value to knowing how one ranks up with other players and because I am pursuing a stronger game I can't help but look to others for suggestions.
So yes I could figure out for myself what is and isn't beneficial for me to learn - whether it's too elementary or over my head, when starting out a study plan I'd rather take a tried and true r approach rather than follow my own unorganized study plan.
This helps me personally with staying on track rather than getting distracted and jumping from study topic to study topic and I can remain focused.
All in all, I'm not one to conform to trodding the beaten path, but at the same time I want to avoid going it freestyle on my own, and just wanted to better understand my skill level so I can plot my study accordingly.
That said, I'm not trying to "filter out" anything based on the number, but I'm trying to "filter out" the things based on what the number represents.
I am not following my number blindly, I know to take statistics with a grain of salt. Knowing where one stands against others can not be ignored when competing with others.
My best example of all of this would be if I asked members here on the forum what they recommend I study, the first question they'd ask, as information they'd need to base their answer on, would likely be my rating.
Fair enough As far as books go, there's the Novice Test in Danny Kopec's Test, Evaluate and Improve your Chess and the very comprehensive Igor Khelmnitsky Chess Rating Exam if you want to get a good approximation without actually playing a Federation rated tournament game.
The other way out is for you to post one of your losses in this thread and you'll find most of the decent folk here who play rated tournaments could size you up rather quickly.
FIDE tournements is 2 hours each player each game. There is alot of difference between both 5 mins and 3 days.

Elo's original K-factor estimation, was based without the benefit of huge databases and statistical evidence. Sonas indicates that a K-factor of 24 for players rated above may be more accurate both as a predictive tool of future performance, and also more sensitive to performance.
Certain Internet chess sites seem to avoid a three-level K-factor staggering based on rating range. The USCF which makes use of a logistic distribution as opposed to a normal distribution have staggered the K-factor according to three main rating ranges of:.
In over-the-board chess, the staggering of K-factor is important to ensure minimal inflation at the top end of the rating spectrum. In theory, it would make it harder for players to get the much higher ratings, if their K-factor sensitivity was lessened from 32 to 16 for example, when they get over rating.
This would seem to hold true, for example, if one analysed the games of a GM on the ICC: one can find a string of games of opponents who are all over A category 10 FIDE event would mean players are restricted in rating between to However, if the player entered normal Swiss-paired open over-the-board chess tournaments, he would likely meet many opponents less than FIDE on a regular basis.
The K-factor would arguably only slow down the increases that the player achieves after each win. The evidence given in the ICC K-factor article relates to the auto-pairing system, where the maximum ratings achieved are seen to be only about In other sports, individuals maintain rankings based on the Elo algorithm.
These are usually unofficial, not endorsed by the sport's governing body. The World Football Elo Ratings rank national teams in football soccer.
Jeff Sagarin publishes team rankings for American college football and basketball, with "Elo chess" being one of the two rankings he presents.
Based on this adaptation, Baseball Prospectus also makes Elo-based Monte Carlo simulations of the odds of whether teams will make the playoffs.
In the strategy game Tantrix an Elo-rating scored in a tournament changes the overall rating according to the ratio of the games played in the tournament and the overall game count.
Every year passed, ratings are de-weighted until they completely disappear taken over by the new ratings.
National Scrabble organizations compute normally-distributed Elo ratings except in the United Kingdom, where a different system is used.
The North American National Scrabble Association has the largest rated population, numbering over 11, as of early In the strategy game Arimaa an Elo-type rating system is used.
In this rating system, however, there is a second parameter "rating uncertainty", which doubles as the K-factor. In the MMORPG Guild Wars, Elo ratings are used to record guild rating gained and lost through Guild versus Guild battles, which are two-team fights which may end in either a win, loss, or rarely, a draw.
The K-value, as of December , is 30, but will change to 5 shortly into the year Prizes for the top players in various regions include holidays and world championships invites.
The widely popular online game World of Warcraft uses the Elo Rating system when teaming up and comparing Arena players.
The ranking tool can even be modified by the players so that they have more control over the math behind it.
WeeWar uses a modified Elo Rating System to rank the players of its online turn based strategy game.
The only difference is that rankings are unaffected by a draw. TotoScacco uses a modified Elo rating system to rank the players of its guess-the-results game, where one has to predict the results of top chess events.

They may choose their events or opponents more carefully where possible. If a player is in a Swiss tournament, and loses a couple of games in a row, they may feel the need to abandon the tournament in order to avoid any further rating "damage".
Junior players, who may have high provisional ratings, and who should really be practicing as much as possible, might play less than they would, because of rating concerns.
Thereafter it remains permanently at For assistance, call or contact us. Rating system model Elo's central assumption was that the chess performance of each player in each game is a normally distributed random variable.
Implementing Elo's scheme The USCF implemented Elo's suggestions in , and the system quickly gained recognition as being both fairer and more accurate than the Harkness system.
The following analysis of the January FIDE rating list gives a rough impression of what a given FIDE rating means: players have a rating above , and are usually associated with the Candidate Master title.
Ratings of computers Several chess computers are said to perform at a greater strength than any human player, although such claims are difficult to verify.
Ratings inflation and deflation The primary goal of Elo ratings is to accurately predict game results between contemporary competitors, and FIDE ratings perform this task relatively well.
The formula for updating his rating is This update can be performed after each game or each tournament, or after any suitable rating period.
Game activity versus protecting one's rating In general the Elo system has increased the competitive climate for chess and inspired players for further study and improvement of their game.
Examples: They may choose their events or opponents more carefully where possible. Chess engines The first and most significant issue is players making use of chess engines to inflate their ratings.
This system calculates the probable outcome of a person's games against other players. Calculating the probable outcome of chess games is one of the fascinating aspects of this rating system: it takes into consideration the fluctuations in a player's performance.
From time to time, we all have bad days when we play poorly. Even when we are at our best, we can still slip up and make a game-losing blunder.
Lower-rated players can still beat someone who is rated higher than them, and the Elo system calculates the probability of that happening.
However, if both players face each other in a match of multiple games, the player with the higher rating probably wins most of the games.
Another feature of this system is that the rating gap between the players dictates how many points they can win or lose.
Since a much higher rated player is expected to win, they do not receive a lot of points for a victory against a player rated much lower.
Their opponent also does not lose a significant amount of points for the defeat. In turn, when the lower-rated player wins, this achievement is considered much more significant, and that player's reward is more points added to their rating.
The higher-rated player, though, is penalized accordingly. Performance rating is a hypothetical rating that would result from the games of a single event only.
Some chess organizations [ citation needed ] use the "algorithm of " to calculate performance rating. According to this algorithm, performance rating for an event is calculated in the following way:.
This is a simplification, but it offers an easy way to get an estimate of PR performance rating. Permanent Commissions, A simplified version of this table is on the right.
FIDE classifies tournaments into categories according to the average rating of the players. Each category is 25 rating points wide.
Category 1 is for an average rating of to , category 2 is to , etc. For women's tournaments, the categories are rating points lower, so a Category 1 is an average rating of to , etc.
The top categories are in the table. FIDE updates its ratings list at the beginning of each month. In contrast, the unofficial "Live ratings" calculate the change in players' ratings after every game.
The unofficial live ratings of players over were published and maintained by Hans Arild Runde at the Live Rating website until August Another website, chess.
Rating changes can be calculated manually by using the FIDE ratings change calculator. In general, a beginner non-scholastic is , the average player is , and professional level is The K-factor , in the USCF rating system, can be estimated by dividing by the effective number of games a player's rating is based on N e plus the number of games the player completed in a tournament m.
The USCF maintains an absolute rating floor of for all ratings. Thus, no member can have a rating below , no matter their performance at USCF-sanctioned events.
However, players can have higher individual absolute rating floors, calculated using the following formula:. Higher rating floors exist for experienced players who have achieved significant ratings.
Such higher rating floors exist, starting at ratings of in point increments up to , , , A rating floor is calculated by taking the player's peak established rating, subtracting points, and then rounding down to the nearest rating floor.
Under this scheme, only Class C players and above are capable of having a higher rating floor than their absolute player rating. All other players would have a floor of at most There are two ways to achieve higher rating floors other than under the standard scheme presented above.
If a player has achieved the rating of Original Life Master, their rating floor is set at The achievement of this title is unique in that no other recognized USCF title will result in a new floor.
Pairwise comparisons form the basis of the Elo rating methodology. Performance is not measured absolutely; it is inferred from wins, losses, and draws against other players.
Players' ratings depend on the ratings of their opponents and the results scored against them. The difference in rating between two players determines an estimate for the expected score between them.
Both the average and the spread of ratings can be arbitrarily chosen. Elo suggested scaling ratings so that a difference of rating points in chess would mean that the stronger player has an expected score which basically is an expected average score of approximately 0.
A player's expected score is their probability of winning plus half their probability of drawing. Thus, an expected score of 0. The probability of drawing, as opposed to having a decisive result, is not specified in the Elo system.
Instead, a draw is considered half a win and half a loss. In practice, since the true strength of each player is unknown, the expected scores are calculated using the player's current ratings as follows.
It then follows that for each rating points of advantage over the opponent, the expected score is magnified ten times in comparison to the opponent's expected score.
When a player's actual tournament scores exceed their expected scores, the Elo system takes this as evidence that player's rating is too low, and needs to be adjusted upward.
Similarly, when a player's actual tournament scores fall short of their expected scores, that player's rating is adjusted downward.
Elo's original suggestion, which is still widely used, was a simple linear adjustment proportional to the amount by which a player overperformed or underperformed their expected score.
The formula for updating that player's rating is. This update can be performed after each game or each tournament, or after any suitable rating period.
An example may help to clarify. Suppose Player A has a rating of and plays in a five-round tournament. He loses to a player rated , draws with a player rated , defeats a player rated , defeats a player rated , and loses to a player rated The expected score, calculated according to the formula above, was 0.
Note that while two wins, two losses, and one draw may seem like a par score, it is worse than expected for Player A because their opponents were lower rated on average.
Therefore, Player A is slightly penalized. New players are assigned provisional ratings, which are adjusted more drastically than established ratings.
The principles used in these rating systems can be used for rating other competitions—for instance, international football matches. See Go rating with Elo for more.
The first mathematical concern addressed by the USCF was the use of the normal distribution. They found that this did not accurately represent the actual results achieved, particularly by the lower rated players.
Instead they switched to a logistic distribution model, which the USCF found provided a better fit for the actual results achieved.
The second major concern is the correct "K-factor" used. If the K-factor coefficient is set too large, there will be too much sensitivity to just a few, recent events, in terms of a large number of points exchanged in each game.
And if the K-value is too low, the sensitivity will be minimal, and the system will not respond quickly enough to changes in a player's actual level of performance.
Elo's original K-factor estimation was made without the benefit of huge databases and statistical evidence. Sonas indicates that a K-factor of 24 for players rated above may be more accurate both as a predictive tool of future performance, and also more sensitive to performance.
Certain Internet chess sites seem to avoid a three-level K-factor staggering based on rating range. The USCF which makes use of a logistic distribution as opposed to a normal distribution formerly staggered the K-factor according to three main rating ranges of:.
Currently, the USCF uses a formula that calculates the K-factor based on factors including the number of games played and the player's rating.
The K-factor is also reduced for high rated players if the event has shorter time controls. FIDE uses the following ranges: .Get Your Elo Rating Here!
