Does “It only takes 4 ounces of pressure for a sword thrust to pierce the body” make sense to you? Because from a physics standpoint it’s nonsense!
I recently came across a statement to the effect of “Having a 4 point target with only 1 point deducted for afterblow is too little. No matter what you still get 3 points and it doesn’t encourage the fighter to protect themselves.”
Learn a little more about some of the physical properties of swords, and why you are probably using terms like ‘Center of Percussion’ incorrectly.
