Nice that he can come back in southAmerica
but he can't count 1000 points at once with these 3 tournaments, maximum 705 points before Indian Wells (and even maximum until october if he goes far in Monte-Carlo and Barcelona), because he has to replace other optionals.
That's the system for top-50 players and that's why it's impossible to "vulture" at this level. "Vulturing" is only important for challenger-players, the use of that notion in the top of the rankings is pure nonsense.
Nadal could be back in the top 4 before RG. Guess it's better that way.
it will be very hard, at the moment, Nadal is 3000 points behind Ferrer for the French open seed.
And being seeded 5 in Indian Wells, Madrid or Roma might give him Djokovic or Murray in quarters (in semi in Miami and Monte-Carlo), which is indeed not pleasant for Djokovic or Murray, but that doesn't change the fact that it's not good for Nadal either.
