My Garmin says that mine is 40 so I'd be in the excellent category for my age. I realize that their are issues with wrist-based measurements of course.
It looks like it would take a fair amount of work to get into the Superior category. Looking at the numbers by age range, it appears that the numbers go down quite a bit because people don't workout as much when they get older moreso than that it's great performance. That is I'm in the excellent category because more people my age are in worse shape rather than me being in better shape.
