Same with women: A woman on the feminine scale is more attractive, but once she gets too feminine no one finds her attractive anymore.
Besides, the whole feminine masculine scale in my opinion doesn't have to do as much with attraction as you claim. A woman with nice features that isn't particularly feminine can be more attractive than a feminine woman with boring, bland, or just bad features. And many times even androgynous women can look good, is it rarer? Yes, but not possible.
And also we all like to see feminine qualities in both males and females. If a man has big eyes, or pouty lips, etc. That is attractive to a woman. Similarly if a woman has a combination body type, such as an hourglass/athletic type, this may be more attractive. This woman is curvy, has a small waist and large breasts, however, her shoulders may be a tiny wider and her legs or something more athletic. Who cares? This woman can be very athletic and stunning at the same time.
Let me give you an example:
