There are six Gambit Infamy tiers, with the first five each having three ranks within. The final rank is called Legend and has only one tier but takes 3,000 points to complete. Only after passing. The person in last had 1k, second was 1,4K and first was 2k. Your team receives a shared amount of their Elo. Let's say you take a total of 64 Elo. You would get around 30, teammates split up the remains. Elo is a tournament and skill based system, getting a win does not guarantee a 30 point boost but maybe a 1 point boost. This guide will tell you everything about the Ranking system in Destiny 2. There are 6 main tires: Guardian; Brave; Heroic; Fabled; Mythic; Legend; These ranks are straightforward. Every player starts as a Guardian and can reach Legend climbing through all these ranks one by one. There are 2 separate ways you progress in the ranking system: Valor and Glory.
What Is The Elo Rating System?
The Elo rating system measures the relative strength of a player in some games, such as chess, compared to other players. Its creator, Arpad Elo, was a physics professor in the United States and a chess master who worked to improve the way the U.S. Chess Federation measured their players' skill levels. He was a solid chess player himself, as you can see from this game he played against a young Bobby Fischer.
The Elo rating system was officially adopted by the U.S. Chess Federation in 1960 and by FIDE in 1970. Many chess organizations and websites also use this system to rate players. On Chess.com, we use a modified version of the Elo system called the Glicko system, which takes more variables into consideration to determine a player's rating.
World Champion GM Magnus Carlsen holds the record for the highest Elo rating ever achieved by a human player. He reached an impressive classical rating of 2882 in 2014. As of June 2020, Carlsen is the highest-rated player for classical and rapid time controls and second in blitz (behind GM Hikaru Nakamura).
- The game adopts an element-themed system, with each rank assigned an MMR threshold, outlining a transparent progression path. Entry-level play opens with Copper rank, followed by Bronze, Silver.
- I haven't seen it yet, but I don't think Destiny has a national ELO ranking system, correct? What's everyone thoughts about this? Probably something similar to Magic's system or Decipher's old system. I think it would be great and help to tie all players around the world together into a single community.

How Does The Elo Rating System Work?
Each player's Elo rating is represented by a number that reflects that person's results in previous rated games. After each rated game, their ratings are adjusted according to the outcome of the encounter.
While people usually think of the Elo rating system as a way of measuring a player's absolute strength, you should note that this is not the case. This system calculates the probable outcome of a person's games against other players.
As a general rule of thumb, a player who is rated 100 points higher than their opponent is expected to win roughly five out of eight (64%) games. A player with a 200-point advantage will presumably win three out of four (75%) games.
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.
To determine the exact amount of points a player would win or lose after a game, several complex mathematical calculations are needed. Do not worry, though, because Chess.com makes them automatically for you. After every rated game, your rating is updated instantly.
Why Is The Elo Rating System Important?
Almost all chess federations and websites around the world use the Elo rating system or a variation of it, such as the Glicko system. This measurement of a player's strength has become the standard in the chess world, so it is the easiest way to assess someone's level of play.
In addition, the Elo system is a statistical model that operates solely based on the outcomes of the games played. As a result, this measurement is more precise than merely judging a player's strength based on subjective and arbitrary elements of the game. If a person makes 'the most beautiful sacrifices' or plays 'the most impressive defensive moves,' for example, this achievement is not reflected in their rating unless they win.
Although this mathematical approach for measuring how good players are is more accurate than ones based on opinion, it is essential to note that it does have its limitations.
Arpad Elo himself recognized that measuring a player's exact level of play is nearly impossible. In one of his articles, he emphasizes: 'The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yardstick tied to a rope and which is swaying in the wind.'
The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yardstick tied to a rope and which is swaying in the wind.

Nevertheless, today's rating systems like the Elo or the Glicko are much more accurate than previously adopted systems and can successfully predict who will win a chess game most of the time.

The ladder is an integral part of the Showdown experience, a driving force for players to continue playing and seek higher achievement and a source of endless frustration for many. Yet despite the ladder's popularity, few know how it truly works, and many often throw around terms like 'ELO' and 'Coil' without really understanding what they mean. While skill rating systems might seem simple—win a game and you gain some points, but lose a game and you lose some points—they vary greatly in implementation, as there are many ways to try to condense player skill into a simple number.
Players who have been around for a couple of years may remember Showdown changing its primary rating system to Elo after using ACRE estimates of Glicko-2 (don't worry if these terms look like gibberish; they'll be explained later), which angered many, as their hard-earned ladder ratings were reset. What's the difference, really? Why was this necessary? And how does this rating system mumbo-jumbo affect you as a player? Read on to find out more.
Rating Systems in a Nutshell
First of all, it's important to establish just what rating systems are and why we need them. Simply put, a rating system is an attempt to quantify a player's skill level. Furthermore, an isolated number representing skill level has little meaning on its own, so it must also be possible to compare these skill ratings with each other in order to determine which of two players is better. This may seem quite complicated and unnecessary, but there are two main reasons why rating systems are used.
Rating systems facilitate skill-based matchmaking, which matches players with other players of a similar skill level. It's no fun to be stomped by a tournament-level player on one's first-ever game, nor is there any challenge for the tournament player in question to win such a game. Thus, ensuring even match-ups is crucial in making the Showdown experience enjoyable.
In addition, rating systems provide a form of progression for the player outside of a single battle: a metagame. Just as the Pokémon games have a map to explore and gym badges to earn, it's necessary to give the player a reason to keep on battling beyond the joy of battling itself. Having a skill rating for players to aspire to raise makes things a lot more interesting for players and keeps them committed to the game even as the novelty of simulator battling fades. Hence, it's clear that rating systems are quite important on Showdown. With this demonstrated, we can now closer examine the rating systems that Showdown uses.
Elo—our current system
First, let's examine Showdown's current main rating system, one of the most popular in the world: Elo. Not to be confused with a British rock band (note the capitalization), the Elo rating system is named after its creator, Arpad Elo, and is used in countless multiplayer games worldwide such as chess, League of Legends, and Counter-Strike: Global Offensive. The system is quite simple: each player starts with a fixed initial skill rating, and winning games earns one points, while losing games causes one to lose points. Winning games against higher rated opponents will earn one more points, while losing games against them results in losing fewer, and vice versa. Furthermore, Showdown also has a rating floor of 1000 (the initial rating), a minimum rating which one cannot fall below even if they lose more points. This ensures that a bad start does not disadvantage a new player or account under the Elo system.
However, this system has a few issues. As one gains fewer points and loses more points if they are rated higher, battling becomes very risky for those looking to preserve their ranking, and those at the top of the ladder are discouraged from battling. Showdown deals with this by using a decay system, which causes those with an Elo rating above a certain threshold to start losing points if they go too long without battling, encouraging them to continue playing and winning in order to maintain their rating. In addition, Showdown also has a K-factor—a maximum amount of points that can be gained or lost per match—which decreases as skill rating increases, making losing a game less costly for high-ranked players. These modifications to the Elo system on Showdown create a fair and transparent rating system that ensures that players can have competitive and enjoyable battles on the ladder.
Glicko and its Estimates
Of course, Elo isn't the only rating system out there. Another alternative, which Showdown used before switching to Elo, is the Glicko rating system. This system improves upon the Elo system by adding a second variable: Rating Deviation, an estimate of the accuracy of a rating. This is used to calculate the variance of your rating, shown beside the ± symbol on your Glicko-1 rating. In addition, unlike Elo ratings, which are updated after every match, Glicko ratings are updated after only two days or fifteen battles on Showdown, with the rating deviation increasing based on the time elapsed since the last battle. To simplify this rating for players, Showdown displays a provisional rating, which estimates the rating that the player will have at the end of the next two-day period.
However, as the uncertainty of a Glicko rating makes it not very meaningful to players, one more step is necessary—the creation of a rating estimate that condenses the rating and its deviation into one value. One common type of rating estimate is a Conservative Rating Estimate (CRE), which provides an estimate of the lower bound of the player's actual skill level. In short, a CRE tells you that a player's actual skill level has a good chance (for instance, 92%) of being higher than the estimated rating. Showdown used ACRE—Zarel's very own Advanced Conservative Rating Estimate—which uses a sliding scale estimate. By increasing the confidence level of the estimate for players with high deviation, ACRE provides lower estimates for inactive players, preventing them from being too high on the ladder.

Using Conservative Rating Estimates of the Glicko system has problems just like the Elo system, especially at the top of the ladder. Players who play a lot often find that their high activity decreases their rating deviation significantly, causing their ratings to change very little after many games. Furthermore, a glitch in Showdown's implementation of Glicko-2 caused some players' ratings to grow to unusually large values, despite ACRE's penalties for inactivity. When those players battled, the ratings of their opponents ended up being affected as well. This led to significant rating inflation which made the ratings a lot less meaningful. In addition, the Elo system was much more intuitive, as players would always gain points after a win or lose points after a loss (under Glicko-2, the reduction in deviation caused by playing a game might cause one's ACRE to increase despite losing), hence Showdown made the switch to Elo over Glicko-2 and ACRE.
Another rating estimate used on Showdown is GXE, the Glicko X-Act Estimate, which was developed by the Smogon mathematician X-Act. GXE provides a more concrete and meaningful estimate of one's skill by calculating their odds of defeating a random opponent on the ladder. Unfortunately, it shares ACRE's disadvatages when a player has high rating distribution and is less intuitive for players more used to the numerical progression of an Elo or ACRE rating. Nevertheless, GXE is probably the best Glicko estimate available and has been used as an intermediate variable in the determination of COIL rating, which is used in suspect testing.
Mystery Suspects
The Elo and Glicko rating systems are meant to estimate a player's skill level, but they aren't very applicable to suspect testing. For this specific purpose, Smogon statistician Antar developed two Mystery Ratings in order to recognize players' achievements on the suspect ladder—COIL and ARMS. After heavy testing, COIL (Converging Order-Invariant Ladder) won out as the better system and has been used in suspect testing ever since. COIL is based upon a player's GXE and the number of games that they played on the suspect ladder. As long as a player is able to maintain a high GXE over many games, they will successfully achieve the requirements to vote on the suspect test. The higher the GXE a player can maintain, the fewer games they need to play, and vice versa—a player with a low GXE (such as 50 or below) will never be able to achieve these requirements.
What This Means for You
Now that you have learned about these rating systems, you will probably still be wondering: What does all of this have to do with me, an average player? Why should I care about understanding these complicated numbers when I could just keep on battling and trying to increase them?
First of all, how one goes about laddering (trying to increase one's skill rating) is greatly affected by the type of rating system in use. If Showdown uses ACRE, as it used to, having a low deviation caused by battling a lot would stagnate one's rating, as it would not change much after each game. In fact, this caused players to 'abandon' older accounts and create new accounts solely for laddering, hoping for a better 'run' during the earlier stages of an account, when the deviation is high and winning has a significant effect on one's rating. In contrast, under the Elo system, one can expect a steady progression in their skill rating as long as they continue to win games consistently, meaning that there is no need to create a new account—winning ten games has roughly the same effect regardless of whether your account is 0 battles or 100 battles old. Thus, players who want to increase their skill rating as much as possible would do well to understand the rating system they use, lest they waste their efforts.
Other ladder-related achievements, such as suspect tests, are also similarly affected. If suspect voting requirements were purely based on Elo, then one would be able to achieve reqs just by winning enough games. However, the COIL requirement in use requires a high GXE to even have any chance of qualifying, meaning that one has to play at a consistently high level in order to achieve reqs, ensuring that suspect voters are good enough at the tier in question to be able to make an informed decision.
On the other hand, understanding the rationale and workings of rating systems can and should completely change one's mindset towards playing and laddering. Many people continue to view skill ratings as a 'score' that symbolises their achievement, a number which they should naturally seek to increase. However, a skill rating is actually meant to quantify one's skill level—something which should remain relatively static. When players get frustrated at their rating increasing by very little after a win or decreasing by a lot after a loss, it is important to recognize that it is not the player that is being rewarded or punished, but the rating system itself. The system has to modify one's ranking by a large amount if its estimate was inaccurate (one loses a game against someone with lower rating ie. a game which one is expected to win), whereas a match that reinforces the accuracy of the estimate (one wins the game which one is expected to win) would change the rating less.
Ultimately, laddering is not an attempt to earn as many points as possible, but rather to discover an estimate of one's own skill level and refine it to be as accurate as possible. One should not seek to reach the top of the ladder just by laddering. Rather, one should first try to find out where they stand in terms of skill rating and then attempt to improve their own inherent skill level by learning, which finally leads to another ladder run to find out their revised skill rating that matches their new skill level, and then the process repeating itself. Understanding these fundamental concepts of rating systems will change one's mindset towards laddering, as well as just play in general. Instead of being frustrated over losing a game or being unable to raise one's skill rating, one should accept that this is what the ladder has chosen and try to take it as a learning experience, using it to improve oneself.

Conclusion
All in all, skill rating systems are more than a simple number representing how long or well one has played, as the different implementations used by various rating systems and rating estimates add a great deal of complexity. Ultimately, this results in a more accurate, yet nuanced estimate of a player's ability to win games. Nevertheless, the inherent randomness present in Pokémon battling itself as well as the inconsistency of human performance introduces too much uncertainty to calculate a truly accurate estimate. While these problems will plague any attempt to quantify something as intangible as player skill, you can rest assured that we here on Showdown and Smogon have done our best to give you a skill rating that, while uncertain, will not be completely meaningless.
