a shooting machine will always place the pressure at the lowest point of the bow's grip
I'm not sure I follow what you're saying there.... My shooting machine has an adjustable grip that can simulate most anyone's shooting style.
Shooting with a high wrist isn't putting pressure low on the grip- but rather just the opposite. Most of the contact and pressure is focused on the high end of the handle and throat of the grip.
Do you mean the
deepest portion of the grip?
