Why can Murray erase Barcelona results? It is a 500 tournament..
There are no more rules on how many 500 events should be on your points like before, they have set new rules. If your a top 30 commitment player, as long as you have played 4 500 events (1 after US Open) you can count any 6 tournaments may it be 250, 500, Olympics, Challengers. It can 6 250 events, or 5 250 events and 1 500 event and so on. However, if you haven't played at least 4 it counts as 0 pointer. so if you only played 3 500 events you will get 1 0 pointer, and so on.
