Age Graded Scores
The age graded score is the perentage speed achieved when compared
with the best in the world for a particular age/gender. So for instance, 
if a 30 year old woman achieved a time or 8:15.0 for 1 mile which resulted in an
age graded acore of 50%, we could assume the world record for a
woman of this age over the same distance is 4:07.5. i.e half the time.
