In the IBF website, there is a list showing ranking points gained from different graded trounaments. At the top of the list, it said a player winning a 7* tourney would gain 600 ranking points. Is there any grand prixs out there that IS graded this high? In fact, the highest grading I've ever seen was only 5*. I guess they woudl need a lot of sponsership to warrant a 7* rating.
