I used it whenever i studied anything, but with a 'recursive' twist. Every time i did repetition, i've made a shorter note about the subject. Then next repetition cycle, i'm reading the note, and making shorter note based on it. and so on. once few cycles i'm re-reading the main starting note i made.
