Why spacing helps
Each review arrives close enough to rescue the memory but far enough away to make retrieval effortful. That effort improves durability.
Use it lightly
Readers do not need a complicated system to benefit. Even two planned revisits after finishing a book can make a noticeable difference.
How to apply this on ReadSprint
These pages should do more than rank. They should help a reader move from a question to a better reading workflow in one sitting.
On ReadSprint, that usually means using summaries to filter books faster, chapter views to focus on what matters, and quizzes or exports to keep the insight useful after the first read.
