Surya's quad toe absolutely should have been ratified. Her quads at the 91 Worlds and 92 Olympics were better than any Kurt Browning ever landed and his were ratified. Just shows how the influence of the people high up in the ISU coming into play IMHO.
That said I never saw her do what would qualify as even a decent attempt at a quad salchow. The ones I saw her try in competition were pretty much a disaester. Maybe there was a good one but I sure never saw it.
