Yeah pennypincher I know the stats seems to inflate sometimes...
For everyone:
Stats 101: A 1 is below average, a 2 is the human average ( yep most of us ), a 3 is outstanding ( an athlete, a pop star, a movie star and so on ), 4 is human's peak ( Olympic Athletes, Nobel price winners ).
Having a 5 in something is above human, it may take centuries to perfect a 5 in skills, only very exceptional humans might reach a 5, Einstein, Mozart maybe. ( i.e. Melee 5, you are better then any martial artist; Firearms 5, Hello SEALs I can shot better then you guys; Performance 5, Hello Hollywood, just give me the Oscars next year....all of them ).
