Why didn't Nadal lose any points this week?

Question

Since Nadal withdrew from Stuttgart and he was the defending champion there, I thought he would lose 250 points, I know they count best of 5 of the small tournaments, Nadal had 6, so they didn't count Rotterdam's 25 points, but now, he has 5, they should count 25 points from Rotternam and not 250 from Stuttgart!!!

Answer 1

Nadal will lose those points next week, becuase of the Olympic Games the calendar 2008 has been changed and Stuttgart 2007 was a week later.

Thats why. We will have the same with Canada and Cincinnati this year. So Roger will lose those points later on.

Answer 2

Nadal didn't loose any point this week because he was able to find them and keep them in his lockers.
