Got a Real World Weapons or Armour Question? Mk X

[Spiryt]

How much does a strike's power vary, just on how solidly it lands? Could a strike end up twice as powerful as what's normal, if the opponent was lined up perfectly?

Well, I guess we should first come with some definition of "power" - this may not be so obvious.

Sheer kinetic energy of bodies in swing? Kinetic energy actually used to do x? Force of impact between x and y?

Anyway, assuming the same individual, with the same weapon, strikes will vary quite a bit obviously - depending on amount of energy and velocity he can achieve, body mechanics, how much of it is at point of impact, if target is moving, and so on.

Most certainly one can produce a blow two times 'stronger' than some of his other ones.
