|ATP Entry System|
|To determine seedings and tournament entry status, it is not practical to use the ATP Champions Race.|
His entry status will be determined by his standing on the ATP Entry System, a rolling 52-week calculation based on the same 18 tournament rules that apply to the ATP Champions Race.
The Race, while indicating the hottest players in the game at any stage, does not necessarily indicate an overall standing in the game.
This is especially valid at the start of the year when early tournament winners may well be leading the Race but are not yet established top players for the purposes of seeding and tournament entry.
