"It is not that English is ambiguous, it is that so few people choose to use the correct words to give the specific meaning they intend to convey.
The diversity of the English language allows you to choose exactly the right word(s) to convey your meaning clearly, but is lost on those who believe that any word can simply be replaced by any other which appears under the same heading in a thesaurus."

Very pompous.

No! Absolutely correct. Any technical reports have to be written in very precise language in order to avoid ambiguity. Just because there may be a preponderance of arty/crafty lefties here that favour loosely constructed sentences, and are happy with approximations of what they wish to say does, not alter this reality. It is a good job airline pilots can follow precise instructions and do not rely on approximations. After all, when flying there is a world of difference between a 1000mm and 1000m when defining altitude.
