Hopefully I’m missing something very obvious.
My problem is that with “Mix new cards and reviews”, new cards take a long time to show up. For example, I I have 60 for review and 3 new, it’s not rare that I’m shown the first new card after 40 reviews, or the first one after 20, and the next one when I have only 10 reviews left. The result is that I end up seeing those new cards too close to each other, which doesn’t help remembering.
(I see my daily 3 new cards of the same note 5 times, one of them Easy and two of them Good twice. I want to see them more evenly distributed between the review cards.)
