This is a follow-up to the recent thread on mixed-DR subdecks and sort order. I participated there; this post is a focused feature request rather than a how-it-works question.
Issue
When studying a parent deck that contains subdecks with different Desired Retentions (DR), the current “Descending Retrievability” order surfaces lower-R cards ahead of higher-R cards. Example: cards around R≈0.78 (from a DR=0.80 subdeck) appearing before cards around R≈0.89 (from a DR=0.95 subdeck). That behavior matches a DR-relative “freshness” sort, not a raw descending-R sort.
Why it matters
-
It’s surprising: the label suggests a simple “highest R first,” but the behavior is DR-relative.
-
It unintentionally penalizes high-DR subdecks during backlogs: high-DR cards sit on the steep part of the curve, decay faster, and get buried when ordering is relative to DR rather than absolute R.
-
Assigning a higher DR usually means “I want to prioritize these.” A DR-relative sort undermines that intent.
Concrete request
Please change “Descending Retrievability” to sort by raw R descending across cards, independent of DR.
Minimal repro
-
Subdeck A: DR=0.95; Subdeck B: DR=0.80.
-
Study at the parent level with “Descending Retrievability.”
-
After a small backlog, observe R≈0.78 from B scheduled before R≈0.89 from A.
