It does depend on which one of the top ten to some extent. If you go to James ruse you would definitely get 99+ with those rankings, if you go to a school that drops in and out of the top ten and is fringing upon it then maybe it would be a different result.
Not sure why everyone is being so pessimistic, I'd say you should get atleast 99.0, how much you go up from there would be up to your performance in the externals
