I think RTK is a useless method. A much more efficient method would be to just Anki vocabulary without learning kanji beforehand.
You do NOT need to memorize the radicals for every kanji, you do in fact only need to be able to recognize the shape in order to read / type. Writing on paper is the only time that radicals actually matter. Most Japanese people forget the radicals of the majority of kanji and just use recognition as well.
It's like in English you don't need remember the spelling of any given word, as long as you remember the word when you see it, except it's compounded by the fact that in English you do need to spell to type, but in Japanese you don't need radicals to type. There is little to no point in memorizing which radicals are used in which kanji. You just need to be able to read it when you see it. Everything else is a waste of time and something you will most likely just forget in the long run anyway.
Even if you wanted to be able to write, I still would NOT recommend learning to write 2000+ kanji before you learn anything else, that's a horrible method. Learn what's actually useful first. Do RTK after you can already read fluently if you really want to.
