I understand the Leitner system as reviewing things at increasing intervals. 1, 3, 7, 14, days, etc. Am I subverting the implementation and effect of this method by studying kanji more frequently than those intervals? In other words, am I defeating the purpose when I don't wait the allotted period of time? I like to be productive and study my flashcards on the train, walking in town, on the pot, etc. But should I be waiting to study those cards until the "correct" day?
Arguments I envision:
By studying kanji more frequently than planned in the Leitner system:
Con:
I solidify the kanji in my short term visual memory but do not allow them to form in my long term memory thus ensuring I will forget them if i DO wait a while to review them.
Pro:
Reviewing the kanji more frequently can only HELP remember them. Practice makes perfect.
