I would caution against dropping writing plain old notes for broader level topics. I've been doing SR for over 4 years, and a few times it's happened that I'm consistently failing flashcards on a particular topic. The way for me to get "unstuck" was to admit I've forgotten key fundamentals, and go back to my plain old notes for a proper review - the way I would do it before flashcards. This gives me the bigger picture, in a logical order.
Going through atomic flashcards did not help me "relearn" something.
