Expanding practice interval planner
Explore a chosen sequence of increasingly spaced review sessions.
How it is calculated
Review intervals are first × multiplier^(review number − 1). Final day = first × (multiplier^reviews − 1) ÷ (multiplier − 1).
Assumptions & limits
This is a scheduling pattern selected by the user, not a proven optimal retention schedule. Adapt intervals to recall, difficulty and actual performance. Defaults are illustrative planning inputs, not recommended minimums or a guarantee of safety.
Planning estimates only. Defaults are illustrative, not personalized recommendations. Do not use these calculations as medical, structural, electrical installation or other safety certification.
