Seasons are aligned by the age each player spent most of that calendar year. Metrics use eligible main-draw results; point statistics use matches with detailed data. 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.
