Methodology
Titles include Slams, Masters, Tour Finals, 500s, 250s, legacy tour events and Olympic gold; Davis Cup is excluded, and walkovers are excluded from all win–loss records. GOAT points value every round reached, scaled per tier (Slam title 2000 anchor; ranking includes Slam champions only, but every player's points are shown here). Elo is a chess-style rating over the full match history (K = 250/(n+5)^0.4); the timeline shows pre-match ratings, sampled. The gold band on the season chart marks the best three-consecutive-year window.
