12.01 Verdensrankingen hvordan gjøres den? Av: Gunnar Solli

Hei Asbjørn

Jeg har lenge spekulert på hvordan man kommer fram til Verdensrankingen for golferne. Jeg synes det virker litt rart at Tiger er såpass langt foran de andre.

Kan du skrive noe om hvordan den settes opp, slik at man skjønner hva som skal til for å ligge på topp.

Svar: Det er en ganske komplisert, men interessant utregning. Fra verdensrankingens hjemmeside har jeg hentet følgende:

The Official World Golf Ranking, which is endorsed by the four Major Championships and the six professional tours which make up the International Federation of PGA Tours, is issued every Monday, following the completion of the previous week’s tournaments from around the world.

The official events from the 6 Professional Tours (US PGA Tour, European Tour, JGTO, SA PGA, Asian PGA Tour and the PGA Tour of Australasia) together with the Canadian, Nationwide and Challenge Tours are all taken into account and points are awarded according to the players’ finishing positions. The points awarded are generally related to the strength of the field based on the number and ranking of the Top-100 World Ranked players and the Top-30 of the Home Tour players in the respective tournaments (event “Ratings”). However, the 4 Major Championships are rated separately to reflect the higher quality of the events together with The Players Championship in the United States. In addition, the Volvo PGA Championship in Europe, and the Australian, Japan and South African Open Championships are allocated higher minimum points levels to reflect their status.

The World Ranking points for each player are accumulated over a two year “rolling” period with the points awarded in the most recent 13-week period doubled – ranking points will then decline in eight equal quarter-year intervals (1.75 after 13 weeks, 1.50 after 26 weeks, 1.25 after 39 weeks, 1.00 after one year, .75 after 65 weeks, 0.50 after 78 weeks, 0.25 after 91 weeks and eliminated altogether after 2 years). Each player is then ranked according to his average points per tournament, which is determined by dividing his total number of points by the tournaments he has played over that two-year period. There is a minimum requirement of 20 tournaments for each 52-week period.

The winners of the Masters Tournament, the U.S. Open Championship, the Open Championship and the PGA Championship are awarded 50 points (30 points for 2nd place, 20 for 3rd, 15 for 4th down to 0.75 of a point for a player completing the final round), and the winner of the Players Championship is awarded 40 points (points are awarded down to 0.60 of a point for 60th place and ties). The Volvo PGA Championship has a minimum 32 points for the winner (points down to 56th place). Minimum points levels for the winners of official Tour events have been set at 3 points for the Asian, Canadian, Nationwide and Challenge Tours (points to 6th place), 6 points for Southern Africa (points to 14th place), 8 points for Australasia and Japan (points to 19th place) and 12 points for Europe and the United States (points to 27th place). In addition the Open Championships of Australia, Japan and South Africa have a minimum of 16 points for the winner down to 0.61 of a point for 37th place and ties. In the cases of co-sanctioned Tour events, the minimum points levels are determined using the “average” of the minimum Tour rankings points from each Tour concerned.

Points are reduced by 25% for tournaments curtailed to 36 holes because of inclement weather or other reasons.
