My take as a technical writer who has edited lots and lots of documentation from non-native speakers, non-professional writers, and so on: if you stumble over the sentence and you have to go back and read it twice or more times to understand what they are saying, then by all means the sentence should be reworded. Otherwise there are probably bigger fish to fry. In this case "learnings" would pass my test. Even if it's a non-standard word I got the gist of their idea without a second glance.
