Yeah that would be a much better way. I'm not sure if the advanced segments set based on a page capture visitor data when they return to the site if they don't visit that page.
March 1st - visitor goes to thanks.php?g=f and gets set as a female visitor based on that page.
March 15th - visitor returns to site, do they still qualify for the female segment? (I'm not sure!) If they don't then my method won't work too well.
