I don't have an exact scintific system, but I always consider:
1. Is she a shopaholic
2. Has she ever read anything reflective
3. Do her eyes dart around the room during a conversation
4. How much makeup
5. Does she giggle when I flirt.
6. What is her cultural background, and is she comfortable with it?
Those are the basic questions in an initial surface evaluation!1
