Advanced Statistics Comparison by Age

Seasons are aligned by the age each player spent most of that calendar year. Metrics are precomputed from eligible main-draw results; point-stat values use the available detailed sample. Bold green marks the stronger value when both underlying samples are sufficient. Lower is better for Schedule because a negative value means a tougher schedule. Career Schedule is normalized per 100 matches.
