ranking is based on the Ranking points of the 3 highest ranked players of
each Association, ranked on the current individual World Ranking lists. Even
if an Association has only one or two players ranked on the individual World
Ranking list, the team of that Association is still ranked. Players not
eligible to represent their Association are not taken into consideration.
To set up the team ranking list, each team is opposed to all the other teams in a computer simulated round-robin, using the Swaythling Cup system of 5 singles matches. In each virtual team match the players are placed in ranking order. 2 points are awarded to the winning team of each of these team matches, the losing team getting 0 points. When there is a tie, which may happen when players of opposing teams have the same Ranking, each of these teams receives 1 point.
The final ranking order is determined by the total number of points earned by each of the teams. Where there are tied teams, in the first instance those virtual team matches between the tied teams are considered to resolve the tie. If there is still a tie, then the total individual matches won against all opposing teams is then considered.
These team ranking lists are taken into consideration for seedings at World Team Championships
