Barely draws back string.
At the peak of the movement, the draw is at its near maximum, he is just as fast as firing than as drawing
he pushes the limb as much as he draws the string to accelerate the firing speed. Very impressive technique, as mentioned in the video it is not for newbies thus any talk about implementing this in cRPG would require the player to have a minimum level of 37 to shoot like this
Penetration power must be quite low like you said mon ami, but against unprotected or badly protected targets I think such a technique would totally own.
