Trenary's short program was pretty weak btw. I don't think she could be placed over either Witt or Manley there.
Kadavy, Trenary, Thomas, and Witt were pretty much equal to me in the SP, but I'd rank them in that order if forced. Midori Ito was CLEARLY the best and Manley was clearly 6th to me (she had the least interesting program and rushed through it, failing to capture any nuances of the music).
Let's compare Trenary (http://www.youtube.com/watch?v=8MqqEmxAQ_c) and Witt (http://www.youtube.com/watch?v=X9m1Z9Izcpg):
On the jump combo I'd score them equally. Trenary's combination was not as clean, but it was much more difficult.
On the double axel, I'd again score them equally. Trenary's landing edge wasn't ideal, but it was bigger and had more flow-out.
Double Flip definitely goes to Trenary. It's bigger and has a difficult air position.
Footwork, Camel-change-Camel, and Flying Spins are pretty much equal. Trenary has a better position in the camel, but also travels a little.
Witt has a slight advantage on the combination spin. It's easier than Trenary's, but cleaner.
So in comparing their technical score, it pretty much comes down to the combination spin vs double flip. Trenary had the second best double flip of all the ladies and Witt's was completely average. I'll take that over Witt's slightly better combination spin.
Of course, that is just the technical breakdown. However, in terms of presentation, I would also give Trenary a slight edge. She had excellent speed (second only to Midori Ito) and her edges were stronger than Witt's. Trenary is giving more energy than Witt in this performance, although because of the couple small bobbles that interrupt the flow, I wouldn't say she gave a better performance. I find the choreography and interpretation of the programs to be pretty much equal. Witt does have more transitions in her program, so it becomes a question of if you prefer more movement vs faster movement and deeper edges. I'll take the latter in this case.
