In some rare cases I see strings in Transifex that contain three numbers. Each number can have three plural forms (one, few, and many). So such string requires 27 translations. For example, transifex / traducir:
It's too tedious to make copy-n-paste many times for the long string and not to make a mistake with plural forms.
Moreover, there is at least one string with four numbers in the source part:
- $EligibleVoters$ voters were eligible, $VisitedSiteDuringElection$ visited the site during the election, $ViewedElection$ visited the election page, and $Voted$ voted / traducir
But it's not too long as previous.
Please do not use strings with more than two (one is much better) numbers with plural forms in the localization engine.
