You know, looking at it from another standpoint, she really DOESN'T have the power of precognition. Her power would better be recollection. The ability to recall anything she has read, the ability to perfectly mimic combat techniques after witnessing them, the ability to recall her past lifes memories and use them to guide her decisions. She hasnt "foreseen" anything once, just looked back and went "oh yeah it be like that before so lets do this"
