This mod hasn't been tested by those of us doing damage research because by the time we got all the other primary damage modifiers, school started for us and we haven't been testing anything for the last two months.

That said, my guess is that this is applied after base damage mods, but prior to Body Part multipliers (you can see the full order over at the Damage page). That is an educated guess but totally not confirmed. It is also unknown as to whether this would be rounded or rounded down but my guess is rounded down.
