Does Recovery Sleep actually make a difference, or is it overhyped?

A systematic and meta-analytical review found acute sleep loss measurably impairs physical performance, and a classic controlled study of collegiate basketball players found extending sleep to 10 hours per night improved sprint times, shooting accuracy, and reaction time — one of the more concrete real-world demonstrations of sleep's performance value. Weighing the data: Recovery Sleep looks an early-stage, lower-priority area for now — the evidence is only moderate (48/100), and its estimated impact (42/100) is on the lower end too.
