Here are the two statements from the Help:
Starting Ease
Controls the easiness that cards start out with. It is set when a card graduates from learning for the first time. It defaults to 2.50, meaning that once you have finished learning a card, answering Good on subsequent reviews will increase the delay by approximately 2.5x (e.g. if the last delay was 10 days, the next delay would be around 25 days). Based upon how you rate the card in subsequent reviews, the easiness may increase or decrease from its starting value.
Easy Bonus [with my bold]
An extra multiplier applied to the interval when a review card is answered Easy. With the default value of 1.30, Easy will give an interval that is 1.3 times the Good interval (e.g. if the last interval was 10 days, the next interval would be around 13 days).
I’ve extracted the statement for Good:
- if the last delay was 10 days, the next delay would be around 25 days
I’m OK with that.
And the statement for Easy:
- if the last interval was 10 days, the next interval would be around 13 days
With respect, I suggest the Easy delay might be:
- (10 * 2.5) * 1.3 days = 32.5 days
Thanks
