Based solely on my observations at the Pre, it
looked like Dragila was utilizing more power in her approach, but she had not zeroed in her timing, yet. She also looked like she was carrying a bit more body fat than I've seen her carry in the past. On her next to last attempt, she would have cleared 15'6".
Svetlana Feofanova was jumping with much less overt power but with considerable finesse. She seemed the flow over the bar as contrast to "jumping" over the bar.
