Dolchstoss Diplomacy Rating System
by Richard Sharp
The game rating is the sum of the player ratings at the time the rating is
Every new player is considered to have played one previous game, in which he
scored 100 points.
For finished games, the game rating points are divided up as follows: 1st 30%,
2nd 20%? 3rd 15%, 4th 10%, others 5 %. The remaining 10% is shared among the
survivors pro rata, based on their supply centre counts. Draws are treated as
you would expect: a 4-way draw scores (30+20+15 + 10+10)14=21.25, etc.
In unfinished games, eliminees and dropouts get their final shares immediately.
Survivors share the remainder: half equally and half pro rata based on s.c.
A player's rating is his total score divided by his number of games.
Experienced player bonus: Players with 5 or more finishes (a finish being
completion of a player's part in a game without dropping out) discard their
worst 20% of scores and the notional first game.
Dropouts: Resigning counts as
dropping out, the only difference being that a p layer who resigns finishes
ahead of a player who drops out in the same season. Drop outs are treated as
having been eliminated in the season in which they drop. They are scored as
usual, but: a) dropout scores cannot be discarded under the experienced player
rule; b) dropout scores are not counted if they would improve a player's rating.
Dropout ratings: Players who have dropped out of at least one third of their
games have a penalty applied to their rating for ranking purposes only as
follows: if they have dropped out of 33-50%, the calculated rating is divided by
n+1, where n is the number of dropouts. Above 50% the divisor is n+2.
Abandoned Games: A game is treated as abandoned if Spring 1901 was not played
(or is not known). Other games are treated as draws between survivors.
Standby players: These are disregarded. if a standby shares in a draw, the
number of participants in the draw is reduced by one; a 2-way draw involving a
standby becomes a win.
Player of record: The player who submits Spring 01 orders is the player of
