My situation...

-I use this site to rewiew RTK kanji and study them.
-It's been about 1 week or 2 since I compleated RTK 1.
-I have been edting my RevTK keywords to more useful ones.example [seat] -> [seat (せき)]
-I am well accustomed to japanse conversations so to it's grammar as I have been reading while listening a japanese stuff even long before RTK 1.
-I do self study only.

So I'm wondering until when should I keep on reweiwing so I can move to the Core anki stuff?

Should I master RTK to be able to recall every one?

Should I start right away?(recalling some kanji would be hard for me since I usually get 70% recall everyday)

Sharing your experiences would be most appreciated or linking me to a related post.

Thx,

Start anytime. The sooner the better tbh. ^^

Even if your recall isn't perfect, what you've done is going to help substantially with vocab, which is the goal, and seeing them in context will help solidify them, and clear up some of the ambiguities etc.

I'd keep up with my reviews, but over time replace keywords with more useful japanese alternatives as you learn more japanese vocab.
