Though challengers don't count, how come exactly 250 spots? Is it always 250 players only?

Thanks~

It doesn't really matter for players that earn a lot of points from challengers and futures, in these cases the race is not very informative.

Count again. There are 280 players listed (31 way tie for 250th). Any player that gains entry to an ATP event and earns a point is on the list. There's no rule that it's 250th place right now for those with 1 point. I just happened that 249 players got more than one point.
