About rating
Rating presented on this page is two fold: total and official. Total rating is calculated basically from any game played by two players on any event sheltered by SASO. Only conditions are: time more than 15minutes plus 30 seconds byouyomi per side and no interference from outside. Official rating on the other hand can only be gained through participation in SASO organized tournament. Game outcome from official tournament counts also agains total rating.

Rating system is ELO, losely based on FESA rating. Starting value for total rating is 400 and current total rating or 400 for offical one (determined at time of first tournament participation).
Unlike FESA, draws do not affect rating - as draws are rare shogi thay may be ignored safely.
Rating is calculated on-the-fly, but it may be subject to change as recalculation of all games (from the very first in db) take place at midnight.
Rating is calculated by player_diff = k * (win - 1/(1+10((player_rating - opponent_rating)/400))). Where player_diff is gain (or lose) by player at given game. k is coeficient between 40 and 10. win is 1 for win and 0 for lose. player_rating is player rating before game and opponent rating is oppenent rating before game.
