Not trying to call into question their methods of study, but what? They are using a calibrated crossbow to study how the points break?

I spent many a day as a young girl trying to throw a spear, being a young girl I obviously was flawed but I did learn something from that, besides the fact that I didn’t have the strength to stay alive from spear kills...it’s very hard to throw a spear straight. Even when the shaft is very straight, it’s like golf, every inflection of your muscle movement affects the trajectory and the shaft definitely hasn’t a straight line. In fact some of the weight of the shaft is different at different portions of it, affecting it’s direction.

How can a machine tell them what the results of a man thrown spear would be...and I say man because I already know, a girl couldn’t kill a rabbit with it for a few months, but hey, it’s nice to be thin;)

The base of the dart is carefully located on the spur of the atlatl, so that it can rotate during launch
