Season Break-Conversion Leaderboard

Share of break opportunities converted per player, from real match_stats rows joined to matches in the season. Breaks are the exact return-side mirror of the stored serve-side columns: a winner converts (loser faced minus loser saved), a loser converts (winner faced minus winner saved), over the corresponding faced total. Only players with at least 50 break opportunities qualify (ATP 2026: 1089 eligible, tops 54.9-60.4). No defaults, no estimates: a player with no stat rows simply does not appear.
