No one is sure of anything only CIC isare you sure, becuase i created my profile just one week ago. my score is 460.
When you create your profile only matters if the cut off on 4th Sept draw is 460. Given that the last cut off was 457. It is expected that a draw on 4th Sept will have a cut off score in this range 455-458. You should be safe given your score is 460.
