Armour divisor and ablative armour

Hi everyone,

I am trying to design an Innate Attack that is intended to whittle
away ablative armour. I intend to go for a crushing attack, but I am
unsure whether such an attack should have a high or a low armour
divisor.

Assume I use the attack against a 3' thick stone wall (B558). The wall
has DR 468 of ablative armour (vs crush attacks etc.). Assume my
attack does 10d cr and that I roll 40 points of damage.

If my attack has armour divisor (10), the wall ends up with DR 47. My
attack does not penetrate, but should remove 40 points of DR. Does it
remove 40 of the 47 DR (after armour divisor), therefore leaving the
wall with 7 DR (after divisor), which is only 70 actual DR, or does my
attack remove 40 points of the wall's 468 DR, leaving it with 428?

Likewise, if my attack had armour divisor (0.1), the wall gains DR
4,680 against my attack. Does it remove 40 of those, effectively
having negligible effect on the wall, or does it remove 40 of the
wall's original 468?

My original idea was that building an attack with armour divisor (0.1)
would be an excellent way to build an attack that is anti-structure
but not very useful against armoured personnel. I would expect the
idea behind high armour divisors to be that the attack penetrates the
armour without really damaging it much, whileas a low armour divisor
attack would spend all of its energy deforming the armour. I am still
reasonably sure that this is the correct interpretation but it never
hurts to ask for a second opinion

Cheers,
Bent D

If you're taking an opinion poll, I'd say option #2: it removes 40 of
the wall's original 468. This does lead to the occasional odd
situation where a high-armor-divisor attack begins damaging HP before
the armor is completely ablated, but that situation still passes a
reality check.
