Stability and due dates are scheduling estimates — not a measurement of your brain. The Science
Choose how much time you have. The app suggests sections from Due Today (honouring the piece filter if one is set) using your sort order from Settings. Estimates are a guide — edit the list before you start.
Minutes are estimates from recent sessions or target reps — not a stopwatch quota. Skip or add sections freely; the scheduler still updates only when you finish each training session.
Choose a piece to log extra practice time. This opens Analysis for the whole piece — time counts in Statistics, the schedule does not change.
Pick the sections you want to rotate through and choose a slice length. Interleave is Analysis after Training: it never changes stability, difficulty, or counters; only a section that is still due today is moved to tomorrow, as with Analysis.
The default order alternates between pieces; you can also go piece by piece or shuffle every round. Prefer mixing pieces rather than staying inside one — that is the point of interleaving, but nothing forces it. Sections may come round several times, so there are no counters, no Gebrian target, and no entry cost. Time is saved as Analysis per section.

No training sessions with logged reps yet for this section. Sessions without logged reps count toward your practice time but are not plotted. The chart appears after you save a Training session with logged reps.
