Thanks for your explanation. Let's say that I have been confused by a confusing report
What's the purpose of reporting such a - huge - number if it's useless?
I understand that if I replace
a with
a, I will get an absurd result to an absurd question. But this is not the same as here. Furthermore "
remplacé 1 occurrence" can just be understood that one occurrence has been replaced. And, if you deal with large numbers, there is no way to check easily that the reporting figure does not relate at all to the effective amount of replacements.
