That chart is, unfortunately, inaccurate. For one, FG has yin and yang facial features, but yang dominates. SD is off too. There is definite yanginess in SD facial features! I have seen charts like that before, but if I went by charts alone, I wouldn't have found myself in a type at all.
The two things I recommend to people are:
1) Google "kibbe face collage" and paste a id-style photo of yourself in the types you're considering to see how the lines of your face (which will be repeated in your body but are easier to see in your face) fit with the ones of the women in that type. You can also try morphing a picture of your face at morphthing.com with celebrities. If you have a good bone structure "match," the resulting morph will be a seamless match of the two of you, neither dominating the other. (My best celeb match is Nastassja Kinski :D)
2) Figure out what you need in clothes and work backwards. I found that I need angles and structure, and in fact, in whatever type I tried on, I would always feel the need to add these two things. What doesn't work is things that are drapey, or clingy without being structured (spandex is okay; jersey is not). These led me to FG, even though I feel like my flesh at my current weight is pretty yin. You can look at photographs of yourself, too. Like Bettycrocker's ability to wear very drapey looks immediately let me know she wasn't FG.
