I unlocked pollution info with console command

It shows that I have ~105M pollution

If I turn off everything but my 3 factories, I get “-17 pollution per tick” and “To zero: 7d 8h”
If I turn on 15 Calciners, I get “Pollution per tick: -1” and “To zero: 28y 155d”

I tripple checked, but 17 times 1 week isn’t 28 years… so I think something in this display is broken

Maybe “per tick” doesn’t account for negative electricity or smth
