Define Average...lol...but seriously woman go by what they hear. Be a good listener and attentive. Work what you have well. Dress well, fresh breath, fresh hair cut, smell good and carry awesome conversation and that will compensate for looks. I mean look at most pimps...they have plenty of women and have been extremely unattractive. lol
That's not how it works. Generally speaking people who are "good looking" are not actually in competition with people of other classes. Realistically if your score was a 5 you would attract more 6's and 4's with the occasional 3 and 7 than a 10 would. While no one doubts that 10s are pretty and attractive despite the sentiment humans actually feel best and most comfortable with people who are about their own calculated values.
It's why 6's end up with 6's and many 10's are single.
