From what I've seen at support groups, the ubiquitous internet pictures and out-and-about, Sherry's 1 out of a 1000 is too high. Even less pass the perceived 100% woman in all social situations test.
But this whole dialog requires a definition for passing and mine is quite strict. The fact that many can blend in or are ignored in a crowd is great, but it's not passing in my book.
Of course if your definition is less demanding then you will consider more as passing.
I don't pass, period. But, I have fun when I'm out and don't worry about second looks. I've found most people quite accommodating. I view it more as "sharing a secret," than as "I'm fooling you."
As Lady Bunny (I think it was LB) said on her blog one time, "it's the rare woman with a perfect face and lips who really looks good in bright red lipstick: most likely you're not her."
