Traditionally, I had always thought that Fluency Fast Tracks and Most Common Word Groupings were created (automatically or not) after a language hit a certain number of sentences. However, I recently noticed that that is not always the case. For example:
German from Japanese: 29,972 sentences – no groupings/fast track
German from Arabic: 11,814 sentences – groupings/fast track available
Tagalog from English: 8,382 sentences – no groupings/fast track
Swedish from Portuguese: 6,896 sentences – groupings/fast track available
So I’m not quite sure what the logic is behind who gets the groupings/fast track and who doesn’t. Consequently, I’m curious - how does a Fluency Fast Track and Most Common Word Groupings get made? What’s the process behind it all?
(Note: This isn’t intended as an angry “where’s my feature” post, this is simply a polite inquiry from a curious user. The examples were chosen completely at random, and I have no stake in any of them.)
