I am lost. Couple weeks ago I ask why Joachim Johansson need to play the qualifing for Indian Wells, he was ranked 50 and his Memphis title come 3-4 weeks before that. someone answer me they go back 48 days, then he was still rank in the 90s. Okay, fair enough. But now for Miami, Hewitt ranked 8 two weeks ago, couldn't defend the IW title and drop to 18, then the ranking is IMMEDIATELY UPDATED and he's seeded 17 in Miami Does different event got different policy for how long to go back to decide the seeding?
