So Im looking for confirmation of my understanding of the system.
Steps 6 Modify Armor and Step 7 Determine Damage (pg 192) are very clear when a weapons AP does not EXCEED the armors listed ratings. The example supports this. But what of the reverse? I have always assumed that any AP values that goes over a defenders armor values counts as extra damage but the book does not suggest that that is the case.
Take for example the Shard Pistol and Shredder. The text clearly says they are very good at penetrating armor (thus the -10 AP) but they do not disperse kinetic energy very well and so do not cause as much tissue damage as kinetic weapons.
If you go by my assumption that excess AP over armor counts as damage an unarmored target hit with a Shard Pistol takes 1D10 + 6 plus the 10 AP points for 1d10+16 damage (avg 21) vs say a heavy kinetic pistol doing avg 15DV. That makes a shard pistol way better on average than every kinetic weapon other than the sniper rifle. This does not even including the short range +1d10 for cone effect weapons.
