I like the analysis for the opportunity to dissect the scene.
I could see the gender prediction working in adults, where you have different BMI baselines. Preadolescence though gender is pretty indistinct. For the most part, a 10 year old boy and 10 year old girl are going be extremely similar in body shape and weight. In terms of forensic data, I'd think Damian would be indistinguishable from Hit-Girl.
While that's certainly an interesting point, I was actually referring to weight distribution in terms of body stance and posturing which is known to vary between males and females in studies where participants ranged as young as nine years old due (according to scientists who know better than me) to in-built neurological rather than physical differences.
