Although I think if these women were too small of a minority, the PUAs would alter their techniques to ones that worked on a more representative sample of women (assuming they're rational; I don't know any, but people in this community seem to have a high opinion of them.)

One phenomenon I've observed is that some of the biggest gurus have begun talking about "higher quality women" or "true 10s" in the last couple of years, where they are meaning "women who have more than looks going for them"... suggesting that as the gurus and their markets mature, they become more interested in other qualities. And these gurus then begin emphasizing personal development, getting one's own life in order, etc.
