And there isn't anything artificial about the top 10... players outside of it refer to their desire to get into it, the first page of the ATP website has the top 10 players listed, media (both specifically tennis and general sports) refer to the top 10 players all the time, certainly moreso than "top 8" or any other cut off/criteria for the current best players in the sport.
