Personally I see little value in SRSing grammar. It seems something that it’s much better grasped by just reading about it and then promply use it (reading).
In the end there’s a switch that it’s needed for learning any language, that’s start using it.
I did a similar post earlier this year
10 months later I went with --> bunpro --> Japanese the Manga Way —> Dictionary Of Basic Japanese Grammar —> CureDolly’s videos on Youtube …
All along I’ve been reading constantly… and in the end now I just review new grammar like any vocab, and try to keep reading, as this has been superior to any SRS, specially in learning the different ways any particular grammar point can be used.
So, this is the anwser I would give my self earlier this year
