An optional feature where reading past your reading goal builds up a surplus that counts towards your next streak interval (day, week, etc.)

For example: If my daily reading goal is 50 pages and I read 70, then the next day carries the 20 surplus and I only have to read the remaining 30. If I instead read 150 pages in a day, then the current and the next two days’ streaks will have been completed.

This way reading past your reading goal feels meaningful.
