Cards remain at the same interval


If I set the starting ease to 150% and the interval modifier to 75% I seem to get strange results:

Many cards seem to remain at the same interval, although it says in the anki manual, that intervals always increase at least by 1 day

“One final thing to note is that Anki forces a new interval to be at least 1 day longer than it was previously, so that you do not get stuck reviewing with the same interval forever.”

These two cards in the pics for example increase the interval in a different way although they are in the same deck:

Can someone make sense of this?

Thank you very much.


I suspect you wouldn’t see repeated days if enabling the v3 scheduler. The Anki v3 scheduler - Frequently Asked Questions
