It took me years (I'm right around 1900 currently after a two-month break doing only review), but I had long periods of time where I was lazy. But it's been nine-ish years since I started studying Japanese in college.

I do not believe anyone can do more than twenty kanji a week consistently. But be advised twenty is very tiresome, and you have to be very organized about it.

Once you pass kanji #200 or #300, there won't really be any general language textbook with a "system" for learning them anymore. You'll have to buy a book specifically for kanji, and I suggest Kanji in Context. It is out of print, but easily the best book for learning kanji.

There are approximately 140 kanji "chapters" in Kanji in Context (but it doesn't cover the newest 100ish joyo kanji). If you do one a week, that's three years, factoring a few weeks for laziness and vacations. One lesson a week is very doable, especially once you're an intermediate student. And the book has as much as five to ten vocab words, on average, for a kanji, so you actually learn them in compounds. You will also learn obscure readings if you wish. For example, 紅葉 is read both こうよう and もみじ. The first is "red leaf" or "autumn-tinged leaves" (literally red + leaf) and the second is "maple tree." The second is a non-standard reading, but I know it by heart because of this book (technically I think people write it モミジ now instead of in kanji).

I cannot recommend Kanji in Context enough. It is hands down the single most important book an intermediate student of Japanese can own. No other single book comes close.
