The measurement of unmodified contents for the whole document (T190283) is not currently calculating the total percentage of unmodified content for the document accurately. Adding one paragraph to the translation and modifying a few words is sometimes allowed even when the limit is set to a strict threshold as mentioned in T219851#5139596.
The threshold should consider the initial content for all the paragraphs and count all the modifications made to obtain the percentage of modification for the whole document. Some paragraphs such as the list of references will be skipped from the calculation, as they are currently skipped for the calculation of the limits on a paragraph basis.
- A section title that has 2 words that remain unmodified followed by a paragraph with 99 words that is rewritten completely will have a 2% (2 words out of 100 total words remain unchanged) of unmodified content for the whole document.
- A document with 2 paragraphs. One with 30 words where 10 remain unmodified and another with 70 words wher 5 remain unmodified, will have a total of 15% unmodified content (15 words out of 100 total words).
