"The seeds are the top 32 players on the ATP Entry System Position (ESP), BUT then rearranged on a surface-based system. A seeding committee is not required for the Gentlemen’s Singles since the seeding order is determined using an objective and transparent system to reflect more accurately an individual player’s grass court achievements: The formula is:
· Take ESP points at 18 June 2007
· Add 100% points earned for all grass court tournaments in the past 12 months
· Add 75% points earned for best grass court tournament in the 12 months before that."
Pour les non anglophones : il faut doubler les points gagnés sur gazon lors des 12 derniers mois, puis ajouter 75% des points remportés lors du meilleur tournoi sur gazon l'année précédente.
"Ladies' Singles Seeding at Wimbledon
The seeds are the top 32 players on the WTA Tour rankings. The seeding order will follow the ranking list, except where in the opinion of the Committee, the grass court credentials of a particular player necessitates a change in the interest of achieving a balanced draw."
Pour les femmes, on prend le classement ordinaire, mais un comité peut faire des retouches. Il me semble que ce système valait aussi pour les hommes il y a quelques années.
