 A player's score is determined by her weighted-point total, which is determined by multiplying her score at each stage by a coefficient that weighs later results more heavily than earlier results.The coefficient used for each point in the finals (4.5) is slightly more than twice that used for each point in the semi-finals (2.2), which is slightly more than twice that used for each point in the preliminaries (1).Thus, a player who wins all of his games except for one draw in the preliminaries will have a higher weighted-point total (45.70) than a player who won all of his games except for a draw in the semi-finals (45.10), and both of those players will have a lower weighted-point total than a player who won all of his games except for a draw in the finals (43.55).
