The 1-10 scale is far too objective. The way I think about it:
1-4: You'd have to give me some powerful hallucinogens to tap that ****.
5: Would do drunk, would not admit to it after.
6: Would do drunk, would admit to it if asked.
7: Will tap sober, though is likely to be a fvckbuddy at best. May introduce to friends depending on her other attributes.
8: The kind of girl I want on my arm when I go out. Hot enough for me to get hard on sight alone, but not so hot that she has an attitude problem.
9: The girl I'd love to have, but I tend to find they have too many psych issues, either low-self esteem, or are daddy's girls, or have majorly inflated egos.
10: A rare sighting, tend to be in the media only.
The other problem is, a static image doesn't always convey the score you have in your head. Some girls are not photogenic, other are very much so.
