Its not just the dropping of the missile table though. Its the fact that you are using the RQ2 table in general. The chest is MUCH easier to hit than represented, missile or melee. What makes the chest (and abdomen) less likely to be injured is defense, whether that be a shield or sword parry, or armor. After the head, the torso was the most common area to be protected (pectorals, breast/back plates and skirts, cuirass').
Now of course, tis easy swap. But its another of the little things that contributes to the perception of the whole.
