Population growth: How exactly does it work?

[Q]

Has increased environmental resistance an effect if the planet condition is optimal?? If so that would be a little odd in my opinion.
And if the planet condition is deadly does increased environmental resistance rise the population growth over zero or has it no effect?

[Fyron]

ER has no relation to planetary conditions; it is just a 1/5th reproduction and happiness effect.

Optimal planets get the same benefit/penalty from ER as any other.

Deadly planets can have positive growth rates either from high levels of ER or from high levels of reproduction (or a combination). In a quick test, 130% reproduction and 100% ER netted 22% growth rate on a deadly planet. Deadly just means the base rate is very low, some negative value.

How does that "Reproduction Check Frequency" factor in?

[Fyron]

Population is increased by 1/10th of the reproduction rate every X turns, where X is that frequency. Thus, in stock, you sort of get the reproduction rate being growth in a year. It is yearly growth, compounded monthly.

If you set Repr. Freq. to 2, it means no pop will grow after one turn, and you will get 1/10th repro rate growth on the second turn. Set it to 3, you get the 1/10th growth every 3 turns, and so on.

Yeah, what Fyron just said. For an example, play Proportions, where population is only increased every ten turns (and then only by a few percent if you're lucky.)

[Q]

So environmental resistance is in fact not resistence to hostile environment (which would be planet condition is SE IV) but just equivalent to reproductionX5.
What is the effect on happiness you mention Fyron?
I learn new things about SE IV even after 6 years!

reproduction / 5

which is not, imho, something that se4 should brag about. I feel like there's so much mystery... why not a tooltip that tells me?
