Scoring

The ranking is equally dominated by the Grand Slam tournaments, the Tour Finals, the Olympic Games, and the year-end ranking. Winners of ATP/WTA 1000 tournaments also receive points within the system. Before the open era, results from professionals are also included.

To preserve comparable scoring potential across different eras, selected historically prestigious tournaments are also included. In men’s tennis, these include Queen’s Club (until 2008), Hamburg (until 2001), and Munich (until 1984). In women’s tennis, the included events are Queen’s Club (until 1973), Berlin (until 2008), Charleston (until 2013), Tokyo (until 2013), Stuttgart (until 2013), Linz (until 2000), and Strasbourg (until 2000).
