Pure Edge Computation
Spaced Repetition FSRS Retention & Review Interval Calculator
Models memory decay curves and spaced repetition scheduling efficiency comparing FSRS against classical SuperMemo SM-2.
Formula:
R(t, S) = (1 + Factor * t / S)^(-Decay); Interval = (S / Factor) * (R_target^(-1/Decay) - 1)
