You have a point about her not being among nobodies in the 40s. I definitely agree with you there, I didn't like seeing here so low on the list. But I was seriously expecting her to be moved up considering her work in the last few months (Vogue Russia cover & ed, Numero December cover & ed, 2 VI eds, Gucci Cruise campaign, decent SS10 fashion week). That's more than what she had when she was in Top 20. Additionally, up until very recently Cat McNeil and Agyness were both in the top 10. Now they're both at 12. When was the last time either of them had a career? And there are other questionable girl placement scattered throughout the list.
But it really doesn't matter, not for someone like Snejana. Whether she is or not on the list changes nothing about her career. I'd rather she not be on the list and get work then be on the list and not do much. And if she ever (chooses to?) comes back full time I'm sure models.com will put her back up like they did with Iselin.
