"+50 Industry per Anomalies on Colonized Planet on System"

This is saying that it's +50 industry for each planet in a system that has an anomaly.  4 planets with an anomaly is 200 industry.

Arcane knowledge is +20 science for each planet in a system that has an anomaly and an additional +20.  That is 4 planets and the bonus for 100.

Then the description is still misleading. "X Bonus per Anomalies on Colonized Planet on System" means that the bonus will be applied once for every Anomaly; it even uses the plural, implying that multiple Anomalies will be counted per planet. A correct description would be "X Bonus per Colonized Planet with Anomaly on System".

I agree that the wording needs to be read closely and could be better, but I find it accurate.

The plural on anomalies actually clarifies it that the wording is correct.  If the bonus was per anomaly on a planet, then each anomaly would contribute.  Since the bonus is per anomalies on a planet, that would mean a bonus for a planet with any anomalies.

At least you convinced me. I adapted your offered solution for my german language mod. Thanks!

I wonder, what is the problem to change a few words in the misleading tooltips... 

And that is not only known issue. there is a buch of descriptions, that are not clear, e.g. Extreme Anti-Gluon beam, Antimatter Lock-on, Annihilator beam 

To answer the question, how does it really work , people spend their time on forums and on ingame tests. 

And testing a game is not fun, it is work.

Sublustris is correct: The majority of the tooltips are generated directly from the modifiers defined in the SimulationDescriptors. This means "changing a few words" of how a bonus displays is not necessarily as easy as it seems.

I agree that the phrasing here is a little confusing (which has always been a problem with the Endless games), but at this point it is unlikely to change.

If there were several effects using the same SimulationDescriptor and you wanted to change the wording on only some of them, I could easily imagine how this would pose a problem.  But presumably all the effects using this SimulationDescriptor scale in the same way, so presumably want to change all game effects that work in this way to have the same reworded tip.  In that light, the fact that it is generated algorithmically from the game data intuitively seems like it should make things easier, not harder (because it implies that you only need to change it in one place to affect all related tips).

Unless you mean that even the substring "Anomalies on Colonized Planet" does not exist explicitly anywhere, and is composited in code from some more elementary blocks?  That's hard to imagine.

I agree with OP that "per Anomalies on Colonized Planet" is clearly a claim that it scales with the number of anomalies (because the word "per" is applied to the noun "anomalies"), and if it actually scales by the number of planets then the tip is incorrect (not merely confusing).
