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.
