My view is a 9 or 10 should be a gal who can make a living off her looks alone. 8's can be super hot, but not making a living off their looks.
10's, 9.s - can make a living off looks alone
8's - hot but are not 'getting paid' hot
7's - normal really good looking girls you would see in your local bar
6's - cute or good looking. Typically marrying type good looking gals.
5's - not ugly but also not what most would call good looking but where the bulk of hte population is
4's and under - Uggo's
In my life I would say I have one 9 and quite a few 8's but mostly 7's. NO 5's or below.
