I might be misremembering, but I don’t think Anki used to behave this way, at least not recently.
Here’s what I’m seeing:
I create a custom deck that pulls cards from one of my subdecks. That subdeck has its own deck-specific Desired Retention (DR) that’s different from the preset’s default DR. But when I study the custom deck, the cards are being scheduled according to the preset’s default DR, not the subdeck’s own DR.
I expected the custom deck to respect the DR that’s set on the subdeck, since that’s how it behaves when reviewing directly from that deck.
Has anyone else noticed this? I could have sworn it wasn’t doing this even a week ago.
I’m on the latest version of Anki.
