Quick suggestion: instead of flat damage, convert damage to dice. So 2.7 might be 1d-1 blunt trauma, whereas something where you did 6 points of BT might be 2d-1.

Adding the variable upper end means sometimes you get by with nothing, sometimes crap happens and you break ribs. I'd also consider (assuming it's not implicit in your stuff) that if armor is penetrated, ignore blunt trauma for certain classes of weapons (mostly piercing for bullets).
