NOTE: the picture is WRONG for ansering :hard for review cards - you DO NOT multiply by the ease!!!
It is also wrong for answering :good The picture: interval = interval card.ease_factor config.interval_multiplier
From the Anki code: interval = (interval + (time.now - card.due)/2) card.ease_factor config.interval_multiplier
It is also wrong for answering :easy The picture: interval = interval card.ease_factor config.interval_multiplier * config.easy_multiplier
From the Anki code: interval = (interval + (time.now - card.due)) card.ease_factor config.interval_multiplier * config.easy_multiplier
NOTE THAT THIS ONLY APPLIES IF TIME_NOW IS GREATER THAN CARD.DUE!!! i.e., you get a little benefit if you are answering a card late.
