4.2 isn't WORTHLESS. I'd say that a score lower than 3 average (15/50) denotes a worthless person. That, and everything MUST be lower than 5/10 (Excluding luck). I mean, someone with a 10 in one thing CAN'T and WON'T be worthless. I think I know about ... 1 worthless person, and here's how I would rate him.
Appearance: 2.5/10 (No better than me.)
Social skills: 2.5/10 (Better than me, a lot more extroverted, but everyone talks about how much they hate him behind his back. Including me.)
Athleticism: 1/10 (He walks with a limp. Sadly, he might get a HIGH SCHOOL LETTER next year for Band, and yet he can't even play his instrument! Need I say more?)
Intelligence: 3/10 (From what I can tell, he's getting about a C- average in normal classes.)
Luck: 3/10 (Better than mine more than likely, but looking at the other things... it can't be TOO much better than mine...)
Adding it up: 2.5+2.5+1+3+3 =12/50, or 2.4/10 overall. And he acts really arrogantly, too.
PS: People with severe genetic disorders (E.G., Trisomy 21) are exempt from grading (It's morally WRONG), except for an automatic 0/10 luck. I mean, if they can barely support themselves, how lucky can they be?
Everyone has their own opinions, no matter how WRONG they are.
