About this calculation
How is this calculated?
Time shortfall = max(target nightly hours − actual average hours, 0) × days.
What does this estimate exclude?
This is arithmetic about hours, not a diagnosis, treatment plan or a reliable forecast of recovery. The displayed thresholds are not clinical categories.
