User post is up to 600 characters, just-in-short:
The official English translation is catching up. It is on chapter 29, while raw is on 32.
The update (English) is ONE chapter per week in three parts. This is abnormally fast, because most series by the company in question likely get updated ONE to TWO parts per week.
A chapter is not really full chapter, mostly partials.
Exclusively recent chapters cost twice. The key is patience or be rich. It is worth it.
