kinda sorta -- in the normal combat system for HARP, heavier armors protect more from damage, and have a higher DB rating.
In RM, there are 20 DB rating (though on the normal attack tables, the protection value is not a linear gradient).
On these, there are 6 columns. each of the six already take into account some of "heavier armor protects better", so the full DB bonus from HARP is not required. However, I also felt that with the Armor By The Piece system that HARP uses, some items will still provide a DB bonus to the character.
The column used for attacks on your character is based upon the armor worn on his torso, the largest part of his bonus. And since the largest portion of your body is now determining the attack column being used, it would not be right to allow the full DB bonus. So I subtracted a value equal to a shirt & helm, the two most commonly worn items (and worked out to be half of the DB of a full set).
In short, the DB adjustments are because the tables themselves provide a damage adjustment based on the armor worn, and the DB adjustment works to balance than back to closer to its original values.
Why not subtract the full suite DB instead? If the column is determined by the armor worn on the torso, there are 3 possibilities:
1. The character is wearing a full suite of this armor type. The column would match exactly, with 0 DB from armor.
2. The character has additional armor by the piece, which gives some better protection than the armor worn on the torso. He will, in many cases, end up with a positive armor DB, using the column for the weaker armor. The positive armor DB will compensate for the possible higher damage. In this case I would treat a negative armor DB as 0.
3. The character has additional armor by the piece with a weaker protection than his torso armor or no additional armor at all. He will, in most cases, end up with a negative armor DB, thus compensating for the lesser damage from the column for the better armor. In this case I would apply the negative armor DB because of the better armor column.
Wouldn't this be more logical?
