Is it somehow possible to get the word count for the translated files? 

What I can see in Trados is always just the word count for the source documents, but more often than not, the target translation is longer then the source. And I need to know the new word count, so I can pay the proofreader adequately. 

I didn't see anything in the API and in the project file in the package I funny enough get a wordcount for the target file, but it's the one from the source file.

This was an EN to DE translation and the Total Words field for the EN file is 0.

Am I missing something here?
