<\/span>Section I. Rating.<\/strong><\/div>
\n<\/span>1.1. To calculate the relative strength of players in sports Dots, the Sevastopol Sports Dots Club (SSDC) rating is used.<\/p>\n

1.2. The rating is assigned to participants in official tournaments held by the SSDC or with its methodological support.<\/p>\n

1.3. A player's rating changes depending on the results of games played in official tournaments and is calculated using the ELO coefficient.<\/p>\n

1.4. Rating calculation procedure.<\/p>\n

1.4.1. The mathematical expectation of the number of points that player A will score in a game with player B is calculated (it is equal to the sum of the probability of player A winning and half the probability of a draw): Ea = 1\/(1+10^(Rb-Ra)\/400), where Ea is the mathematical expectation of the number of points that player A will score in a game with player B; Ra is the rating of player A; Rb is the rating of player B.<\/p>\n

1.4.2. The new rating of player A is calculated using the formula: Ra\u2019=Ra+K(Sa-Ea), where K is a coefficient equal to 10 for players with a rating of 2400 and above, 20 for players with a rating below 2400, and 40 for new players (the first 30 games since the rating was assigned); Sa is the number of points actually scored by player A (1 point for a win, 0.5 for a draw, and 0 for a loss); Ra\u2019 is the new rating of player A.<\/p>\n

1.5. The rating is divided into two categories: classic Dots and rapid Dots.<\/p>\n

1.5.1. Classic Dots are a rating assigned to participants in official tournaments with classic timekeeping.<\/p>\n

1.5.2. Rapid Dots - a rating that is assigned to participants in official tournaments with \u201cblitz\u201d and \u201crapid\u201d timing.<\/p>\n

1.6. A player participating in an official tournament for the first time is assigned an initial rating in the corresponding category.<\/p>\n

1.6.1. The initial rating value is 1200 points.<\/p>\n

1.7. All games played in an official tournament are rated, meaning they result in a change in the players' ratings.<\/p>\n

1.7.1. If the regulations of an official tournament provide for replays of drawn games, both these games themselves and all their replays are rated.<\/p>\n

1.7.2. If the result of a game is annulled by the decision of the arbiter of an official tournament, only its replay is rated.<\/p>\n

1.7.3. A game, the result of which is determined without play due to the absence or disqualification of a player (players), is not rated.<\/p>\n

1.8. The calculation and assignment of the rating is carried out by the relevant official of the SSDC.<\/p>\n

1.8.1. Changing the rating in any way not provided for by these Regulations is not permitted.

<\/span>Section II. Sports ranks.<\/strong><\/div>
\n<\/span>2.1. A sports rank is a mark of distinction that reflects the level of a player\u2019s athletic achievements.<\/p>\n

2.3. Hierarchy of sports ranks (from lowest to highest): third-class, second-class, first-class, candidate master, master, honored master, grandmaster.<\/p>\n

2.3.1. Abbreviated names of ranks are written in Arabic numerals and Latin letters (from lowest to highest): 3, 2, 1, C, M, H, G.<\/p>\n

2.3.2. If a player has participated in official tournaments, but there are no grounds for awarding him a sports rank, he is considered to be of no rank (abbreviated as N).<\/p>\n

2.4. The grounds for awarding a sports rank: a player achieving a certain rating (in the \u201cclassic Dots\u201d category) or winning prize places in official tournaments of various categories.<\/p>\n

\n<\/div><\/div><\/span><\/p>\n

<\/span>Section III. Tournament Categories.<\/strong><\/div>
\n<\/span>3.1. Official tournaments held by the SSDC or with its methodological support are divided into categories depending on their representativeness and sporting value.<\/p>\n

3.2. Categories of official tournaments: highest, first, second, third, fourth.<\/p>\n

3.3. The highest category includes official tournaments, the conditions of which do not create restrictions on the maximum skill level of the participants, the quality of the game, and the objectivity of the result.<\/p>\n

3.4. If the conditions of an official tournament imply restrictions on any of the specified parameters, then its category is reduced by a number of steps corresponding to the number of limiting factors.<\/p>\n

3.4.1. Factors limiting the category of an official tournament:<\/p>\n

\u2014 an upper limit on the rating and\/or sports rank of the participants, which cuts off any number of stronger players;
\n\u2014 gender restrictions that exclude players of any gender;
\n\u2014 age restrictions that exclude players of any age;
\n\u2014 territorial restrictions that cut off players living in any territory or outside of it;
\n\u2014 strict restrictions on playing time (\u201cblitz\u201d or \u201crapid\u201d);
\n\u2014 a format in which a participant does not have to meet with any of the other participants during the tournament;
\n\u2014 correspondence form of implementation.<\/p>\n

3.4.2. For official tournaments that are held in a league format with division into divisions depending on the skill level of the players, the category is lowered by one level for each subsequent division after the highest.<\/p>\n

3.4.3. If the conditions of a tournament require the participation not only of a pre-defined group of players registered in accordance with the general requirements, but also the guaranteed participation of a specific player(s), conditioned by the decision of the organizer, regardless of his (their) skill level, the moment of the decision on admission, and actual admission, the category of such a tournament is reduced by two levels.<\/p>\n

3.4.4. If the upper rating threshold and\/or sports rank of the participants stipulated by the conditions of the official tournament excludes players with a rating of 2200 and above and\/or players with the sports rank of candidate master and above, the category of such tournament is lowered by two levels.<\/p>\n

3.4.5. If an official tournament is held for the purpose of determining a challenger for a match with the current holder of a title, its category is not lowered by the fact that the title holder is unable to take part in it.<\/p>\n

3.4.6. Matches between two players, except for title matches, cannot have a category higher than fourth. The category of a title match is determined by the general procedure.<\/p>\n

3.4.7. The organizer of an official tournament has the right to assign it a lower category than that required by these Regulations. Arbitrary assignment of a higher category is not permitted.<\/p>\n
