I remember Cohen's, Slutskaya's, and Suguri's SPs very well. I do not remember Shizuka's at all. I do remember it was just a shortened version of her flat LP she had all season before she smartly changed her routine to Turandot where the music did most of the work in selling that routine.
Shizuka did have great skating qualities (like speed, skating skills, spins and spirals that could compete against Sasha and Irina in levels and GOE). I think her being able to match Sasha and Irina's elements is what got her the tie. They don't care about performance quality. Irina had little-to-no musical interpretation going on and really lost whatever finesse she had on her elements by that point in her career, and Sasha's skating was a bit smaller and she had a double axel that almost went badly. That could explain the closeness in scores.
