Impossible since you have to rate a man on multiple dimensions first, then develop an "overall" impression from that.

ie.

Voice - deep, high, flamboyant, commanding

Hair - Norwood rating and quality of style

Facial hair - adequate or not

Height - short or tall

Face - symmetry, proportion, width-to-height, jawline

Race - obviously white is on easy mode, blacks/indians/chinese are about equally damned

Build - wrist circumference, muscle mass, and body fat

For example, I am 3/10 voice, 4/10 hair, 3/10 facial hair, 4/10 height, 4/10 face, 3/10 race, 4/10 build. Add it together and I'm pretty fucked. I'm not sure what my overall rating comes to from all that. Somewhere between a 2 and a 4.

You would need to come up with scales for each individual parameter.

eg. 1/10 voice is Gilbert Gottfried. 3/10 is David Bekham. 7-8/10 is Vin Diesel. The guy that played that black detective Mike Anderson on Dexter is probably 9/10 voice - deep, commanding, and alpha as fuck.
