Anki 2 Add-On that iterates through each deck options group in your collection and sets the initial ease factor to the average ease factor of the mature cards (cards with intervals > 90 days) in that deck optons group.
Settings are calibrated each time a profile is loaded (at startup).
See Post: Anki's Starting Ease Factor Settings for the rationale behind this.
Compatible with both Anki 2.0 and Anki 2.1 (if the experimental scheduler isn't in use).
From within Anki: Tools >> Addons >> Browse&Install. Enter code: 633293039
Otherwise, clone this repository to your addons directory (for Anki 2.0 ~/Documents/Anki/addons, for Anki 2.1 ~/Documents/Anki/addons21).
