Hmmm... Nope! This formula should apply to HtH combat: where min_damage_of_weapon=1 and max_damage_of_weapon=2 if the critter in question has no weapons. There is no reason not to allow HtH bonuses for weapons such as Power Fist. And I suggest that 'heavy_handed_bonus' should apply to Weapon Melee Damage. These things are related, aren't they? Because Heavy Handed trait is so unattractive, I would further suggest to treat it like 2 levels of HtH_dam_perk, but I'll leave this for others to decide.
