Lukesdad, it is more a question of sensibility than sensitivity.
If I told you that tops was 200 (it isn't) you might assume that anything close to 112 was as good as a fail. (Under confidence).
If I told you it was 140 (again it isn't) then you might assume you were better than you actually were. (Over confidence).
If you know you are well above the pass criteria then you can relax in blissful ignorance because, as others have said, a high PA score is not the be all and end all.
