True, although apparently Batman and Moon Knight can do predictions of gender based off of a combination of the weight distribution, height and potential age that you'd get off the Heely marks, the sword execution and the two gunshots.

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.
