Calculating "Power Level" or "Combat Score" in GURPS

[Talonos]

I've been giving them the full CER, which, indeed, has led to a lot of head scratching at times. For instance, they still haven't figured out that "HP restored by your best healing spell" is factored into the "Threat Rating" equation, and still think the NPC healer they found has some hidden secret martial art powers (or something) that he's hiding, which explains the healer's unexpectedly high Threat Rating.

If they find out and object to healing's inclusion in the threat formula, my planned response is: "If healing's not a threat, then why do people always try to take out the healers first?" ;)
