Whenever I am in combat I find it really hard to calculate the damage my NPCs receive, because it has a lot of small steps: account the damage the PC did, subtract any Pen the PC's weapon may have to my NPCs AP, then subtract any AP left to the raw damage the PC did, and then subtract my NPC's TB to whatever damage is left.
The calculations are simple, but I get lost easily due to the amount of steps and the pressure I feel because I don't want combat to be slowed down, so I could really use a program that could do my bidding. I've tried Excel sheets, but I'd have to change numbers for every weapon and I'm not very skilled at that program either.
This program should have: An NPC "section" where I could choose how much AP and TB does it have, another "section" where I put the weapon's characteristics (Pen, special rules), and finally a wound counter of some sort that showed me how much HP does the NPC have left. The best would be the ability to save templates with different weapons and NPCs. And if I can dream, it would also display the appropriate Critical Damage text for every -1 to -10+ wound.
