Serve reliability

Double faults per match, from point-by-point where tracked and from the note N DFs line otherwise. Lower is better, so a negative Δ is an improvement. Point-by-point rows count the whole serving side, so doubles uses the note’s own count only — a doubles match without one is left out rather than counting a partner’s double faults. Singles prefers point-by-point.
