Re: Tennis Tipping Davis Cup Nations Ranking - July/2009
Tennis Tipping Davis Cup Nations Ranking - Overview
The TT Davis Cup Nations Ranking is used as the sole criteria for seeding at all levels of the Davis Cup competition. However seeds one and two in the World Group shall be the Finalists of the year immediately prior to the year for which the seeds are being selected, and seeds 3-8 shall be in accordance with the latest Ranking. The ITF Davis Cup Nations Ranking is published following every World Group round. All nations are ranked.
The ITF Davis Cup Nations Ranking measures the success of all Nations participating in the Competition over a 'rolling' four year period with recent performance weighted more heavily.
After each round the ranking period adjusts and any results outside the adjusted four year period drop off. At the same time points from the same round for the three previous years are reduced as per the points table below. Therefore, 100 points would become 75, then 50, then 25 over the four years.
The points stated are awarded to the winning team in that round. (A nation losing in the World Group first round, for example, earns 0 points for that tie.) In addition, any Nation that defeats a higher-ranked Nation receives bonus points according to its opponent's ranking as detailed in the table below.
