Function of reducing fuel and supply consumption

[Cpack]

Question for Supply and also fuel values:

If I have a submarine with supply_consumption of f.e 1.0

1. Tech
command = { type = supply_consumption which = submarine when = now value = -0.1 }
2. Tech
command = { type = supply_consumption which = submarine when = now value = -0.2 }

After the first tech, I have a supply_consumption of 0.9 right ?
But after getting the second tech, does I get 0.7 or additional 20% of 0.9 which means 0.72 ???
In this example it doesn’t matter, but if you have much more techs, in the first example you can go negativ, or at least to zero, while in the second example (%) you never reach zero.

How does it work ???

In some techs there’re behind –0.1 5%, sometimes 20%
command = { type = supply_consumption which = submarine when = now value = -0.1 } # 5%
command = { type = supply_consumption which = submarine when = now value = -0.1 } # 20 %
That’s confusing me !!!!


Thanx

Modifiers always add up, they are never calculated percentagewise.

Except for the percentage modifiers

But for supply, yeah, it's incremental applied to the supply cost of the unit.

So if you have a tech that reduces supply cost for a unit by -0.1, and the unit supply cost was 2.0 beofre, it'll be 1.9 after.

I was under the impression that even the percentage modifiers were also additive.

So the IC bonus techs when are x % more of what your 'base IC' is before any actual IC tech. So when you get polyurethane that is not 5% of your current IC but 5% more of your base IC. Since you already have the earlier 3% IC tech, you get 1.08/1.03 = ~.485% increase of your current IC (assuming you don't have any other IC increasing techs).

You are correct. Modifiers are always added up.
