What Spun says is right, and yes Miki is not content primarily with herself avoiding 3-3's, so she was doing 3lz-3lo-3lo in practice for sometime after the worlds.
She seems to be taking a break right now, but she'll soon want to prove she has not given up on it, I believe.
And oh her quad ... it seems to me that it's sort of a self-encouragement.
I can't forget how Miki burst her joy right after her free at GPF'08 in which she stayed on her foot with her 4S< .
Even though it has a < , and though maybe not much of a meaning, this is indeed recorded officially in the protocol sheet as a 4S attempt without fall.
