When people here refer to RTK, they are just referring to RTK1. I don’t think anyone has tackled RTK2.

I went through the entire book as prescribed by Heisig. See the keyword, write a story, write the kanji, SRS it as assigned. Sheepy can probably answer the question better than I as he’s moved beyond RTK and is using it in the real world. I’ve been through all of the kanji but am trying to catch up on my overdue Anki reviews. :P

Good luck!
