Every number is drawn from a deep sample of hand-charted matches.
Serve placement shows the share of first & second serves aimed
wide / body / T on the deuce and ad courts — how a player opens the point.
Return depth splits returns into shallow, deep and very-deep, with
Deep+ the combined deep share (how far back they push the returner off the baseline).
Rally gives winners and unforced errors per 100 shots, their ratio (W:UE), and an aggression index (how often the player tries to end points early). Charting is volunteer-driven, so lower-ranked players carry small samples — use the
charted-match gate to keep the board honest; players below it are hidden. Descriptive style metrics only —
not a betting line. Refreshed nightly.
