I’m having a hard time understanding the “Reviews” options page as I recently started to adjust the “Interval modifier” percentage. Here is my observations and thoughts so far:
In one of my decks I’m using an “Interval modifier” of 65% to shorten the review intervals. The “Easy bonus” is set to 130%. But I’ve observed quite a few cards that showed me the exact same time interval in all 3 categories (Hard, Good and Easy), mainly above the 1-month mark (I remember seeing cards with all three options set to 1.1 months, all three options set to 1.3 months and so on). Other cards showed the same interval for two out of the three options and a different interval for the third one.
(Reviews were done on Anki for iOS 2.0.63 (20063.6). using the default scheduler.)
-> I consider this a bug because my understanding is that we have a default interval which is used for Good (in my case it will be 65% of the double of the previous interval for that card), and from this default interval we derive the Easy and Hard intervals. Therefore Easy should always be Good * 1.3 with my settings, not identical to Good. Also, no matter the setting, Hard should always be below Good, not equal to Good.
I wanted to counteract this issue by adjusting the Hard interval with the beta scheduler (I looked at it in the Desktop application), but when I opened the settings page I noticed that the default setting was 120%. (The documentation confirms this default value and my understanding: “eg with a default 120%, a card with a 10 day interval will be given 12 days”.) But we are talking about the Hard interval here, which is supposed to be shorter than the Good interval? How can it be 120%? I had expected to see something like 80% or 70% here. Does this mean once the beta scheduler is enabled, I need to go through all of my decks’ options and adjust the Hard interval because the default setting turns the Hard button into another Easy button?
Thank you for any insights!
