Armor mods, And projected cost. Options

[Rolemodel]

It's been a while since I've worked with constructing armor. So. Bear with me.

I'm looking specifically at Thermal dampening. Cost is noted as '+(1500xRating)' with 'SI: +2'.

Now. Is this to imply that the total cost of the armor is calculated as follows:

Armor base cost x (SI+2) + (1500x Rating)

Or.

(Armor base cost + (1500xRating)) x (SI:+2)

God it's late here. My head is spinning with exhaustion. Too much math on an Easter sunrise.

the way i would rule, it as follows

Lets say you have some armor, that bought from a store/fixer, is 1000 nuyen, with an SI of 1 (so no multipler)

now you want to had rating 3 thermal dampening, the new armor would cost [1000+ 4500 (1500*3)]*3 (previous si 1+2), or 5500*3, being 16,500 :nuyen:

Wich means you'd rule it as the second example.
This is also how I'd rule it.

Ditto. As best I can tell, SI is done off of total cost.
