DC doesn't offer ranking points?
Starting this year those who play in live DC rubbers may get ranking points depending on what other 500 tournaments are counted:
Q. What are the ranking rules for players who compete in Davis Cup?
A. Davis Cup points are awarded for World Group and World Group playoff ties only. Points allocated are as part of the 500 point category. Davis Cup does not count towards a player's commitment to the 500 category. The points accumulated in the four ties within the previous 52 weeks can become part of a player's 500 category if:
1. Player has not more than three 500 results within the previous 52 weeks and Davis Cup result(s) is better than lowest best other.
2. Player has four 500 results within the previous 52 weeks and Davis Cup result(s) is better than the lowest 500. Also, 500 0-pointers cannot be replaced.
