FAQ

What is Marathon?

Marathon is a long-term open tournament, usually played by periods. Marathon is opened to all players, with no restrictions with respect to participation, or the number of accounted within a period games.

Player's Score

The player's score within a period is a weighted sum of four components: 50%*average_TP (taken for all games) + 50%*average_TP (taken for best 10 by TP games) + 1%*number_of_games + 10%*average_TP_opponents (against whom player played).
Comment: TP stands for total_points, the sum of game_points and bonus_points, which players receives from each game played.

To be rated, 26 games within the entire 2024 year have to be played by the player. While determining the player's score, all missing to the amount of 26 games will forceably be counted as having 0 TP.

For the sake of simplicity, all the components are rounded to the two digits after decimal point. For tied results number_of_games is used as an additional criterion — the lesser is that number, the higher player's score is.

Ranking

All players' scores within the period are then ranked (including breaking-ties algorithms). Each player, who played the established within a period minimum number of games (26), is called as "qualified player". Each "qualified player" receives so-called "Basic Rank" (BR) according to the formula:
BR = 1000*(number_of_qualified_players-player's_place+1)/number_of_qualified_players, rounded to the closest integer number

All players who have not played within a considered period the established minimum number of games (26), receive BR=0.

Games Disqualification

To enforce "healthy" competition any game with seemingly unequal opportunities to compete should not be counted (disqualified). Thus, any games having "excessive" number of "automoves" (that is moves when system plays instead of disconnected player) should be disqualified.

SBR Auto-Marathon Games Disqualification Criteria:
