Earlier quoted context omitted.
This is just something that I read somewhere so don't take it at face value, maybe someone who knows the issue better can confirm or deny it. But I remember reading that in Asian countries like China and Japan, they tend to base the selection of translators on knowledge of the source language, not the target. That is, they get the translator with the best knowledge of Chinese even if their English is broken.
So is this basically saying that a grammatically incorrect, but factually correct translation is better than a grammatically perfect, but factually incorrect (as the source text was not understood) translation?
In the Netherlands, correct grammar is only a small part of the final score, and what is given far more weight is how well one is able to understand the speaker and convey one's thoughts to the listener, and far more emphasis is placed on practicing conversations, even though they not be grammatically sound, which in Finland would be considered walking before having learned to crawl, but it seems to work.
