While it doesn't count as official on any tour, the Chevron World Challenge has received rankings points for three straight years under the provision it has a qualifying standard and the two sponsor exemptions are in the top 50 in the world.
What caused his swift ranking rise had as much to do with only playing 27 times in the last two years, giving him the minimum 40 divisor when points are calculated.
There will be some slight changes next year for Woods' event and for the Nedbank Challenge in South Africa, which Lee Westwood won and received 38 ranking points.
The Official World Golf Ranking board, at its annual meeting in July, approved a modification for tournaments that have fewer than 30 players.
Those events will no longer get the "home tour" rating component - essentially bonus points that depend on how many players from the host tour are in the event.
Without the home tour component at Chevron, the winner would have received 40 points, instead of the 44 that Woods received. Woods would have gone to No. 25 instead of No. 21.
