How the energy consumption of battle modules per Zet's is calculated.

On the example of a crystal suppressor:

100% of energy is 2995.

If I set the crew settings to reduce power consumption by 29%, it shows me consumption of 2139 when it should be 2126.

If I set the power consumption reduced by 25% in the ship settings, it shows me 2246 and that is correct.

If I have reduced power consumption on combat modules enabled in crew and ship settings, I should have 54% reduced power consumption in total, which is below 1500 (1378 to be exact), but it shows me 1728.
So how is this calculated?

Read this please 

 

Then I’m going to ask someone here to count that power consumption.
I have a Neuroaccelerator set up in my crew
“Sting II” and on the ship reduced energy consumption of modules -25%.

I actually have a reduced energy consumption of 42%.

Looks like a node changes the base value for other calculation purposes.

Also that -29% is not exactly -29%.

 

So:

Base = 2995, with node newBase = Base * (1 - 0.25) = 2246

crew modifier: -0.29

newValue = newBase/(1- crew modifier)

so:

newValue = 2246/(1-(-0.29))=1741

Looks like there is a rounding involved, because it’s more like:

newValue = 2246/(1-(-0.30))=1728, which is the value displayed.

Ok, dzięki.
