[@Doc Doctor] I didn't see any question above, "Just one more question," but her hand would be at three quarters of the length (so I'd say two feet between the tip of the spear and her hand, and about a foot and four inches from her hand to the tip of the axehead) and the length of a forearm (around seventeen inches sounds right to me for a five foot ten woman) so I'd say Zande is three feet and five inches from her left flank, and the rest of her torso minus bust is around fifteen/sixteen inches to the opposite flank, so anywhere between three feet and five inches to her leftmost and closest to Zande point of, "torso," and four feet eight/nine inches to her furthest away, "torso," from Zande's perspective, if that makes any sense. Her left foot is leading and across her right in the Chinese style (picture below) not because she was taught to fight that way, but because she was still working to keep her left flank opposite from Zande's face/blowgun and it felt like the most natural stance/stepping point when I worked through it. So her left foot has just planted, and her right is couched behind, though not flat so that she could still step back and around or launch a spinning donkey kick or something (not that she'd have the background to think about doing that) So technically her right foot is closest to Zande, but her left is leading (she side-stepped so it isn't as straight forward here as lead foot is closest). She isn't much of a sprinter, so I'd say that she's hitting around fifteen miles per hour at top 100m dash kinda sprint which is super standard for an athletic woman below thirty five (for reference the London Olympic Women's qualifying 100m speed was 19.8mph. 

The feet would be like this, but standing higher/taller at the legs and hips and obviously raised higher at the arms and shoulders as Aibhilin is swinging for Zande's head and not trying to whack his leg. Also her torso is quite far forward, Aibhilin's would be tucking into the blow and bent slightly at the right hip while thrusting it forward and into the hit.
