SR5 : Armor rule Stun vs Physical Options

[Dracolarme]

Hi,

I'm participating in a game and we are a bit confused about some rules around armors. If someone could clarify, we would be grateful.

We have one character who has 12 physical box, and 9 stun box on his condition monitor.
He has 16 for armor and 6 body.

There is a rule that states, that if the damage you receive is not higher than your armor rating, you suffer stun damage instead of physical.

So here's an example :
I shoot him with my ares predator V, i get 6 hits, and he gets 2 hits on his defense roll. So I do to him 12P damage. That means it is stun damage.

He gets a 21 (16 armor and 6 body -1 Armor piercing for that pistol) dice pool for damage resists. So 12 minus the number of success on that pool, will represents the stun damage he receives.


So a character like that, that has a lot of armor is mostly always going to receive stun damage, but as soon as your stun condition monitor is full you fall unconcious...

Have I understood the rules correctly?

Does that means that something like a troll with a focus on the physical attributes and in full combat armor is gonna near never get physical hit, and that he'll soon fall unconsious, since he doesn't have a big stun condition monitor?

Thanks in advance for the clarifications.
