You have 5x9 (45) base production + 5x1 because of anomaly and 5x2 because you build the crop improvemt. A total of 60. As long as 5 pop consume 1 food each per turn it's a total of 55 food, not?

Strange. I thougth another possible answer.

Food is 8 base plus 1 from anomaly plus 2 from system improvement = 11 thus x5 = 55

I dont think pop's consumed food will be counted in the planets FIDSI stats.

See anether example:

Would be useful to know more about the population you have on this planet. I.e. Riftborn population doesn't need food.

Indeed , there is consumption , but is displayed in the System  panel info , not in the planet info .

Could you upload a save file for your thread starting situation?

I think there was misunderstanding. The stats in my initial thread post are from the planet, not from the system , so the consumption argument is not valid.

According to wiki default food value for Terran planet is 8, so the 9 in screenshot is native 8 + 1 from anomaly, + 2 from improvement it's 11, so it checks out.

Same for Raia in second example, default Terran yield is 8-3-4-4, but it shows output already taking into account the modifiers, which makes sense, though the wording may be confusing.
