      "trap": 1,
      "notes": "20% win rate (+3.3pp vs baseline). Single most valuable draw in UK racing. Inside line bypasses first bend crowding. Best suited to front-runners and dogs with natural rail affinity.",

      "trap": 2,
      "notes": "17% win rate (+0.3pp vs baseline). Traps 1–2 collectively dominate sprints. Benefits from proximity to rail without the squeeze of trap 1. Reliable second choice.",

      "running_style": "Early pace / stalkers",
      "rail_advantage": "Strong — near-rail secondary advantage"

    {
      "trap": 4,
      "notes": "16% win rate (-0.7pp vs baseline). Slightly outside center; vulnerable to bend crowding on tight ovals. Requires runners with good acceleration or tactical race sense.",
      "win_pct": 16,
      "running_style": "Mid-pack / dogs needing room",
      "rail_advantage": "Neutral to slight disadvantage"
    },
    {
      "trap": 5,
      "notes": "15% win rate (-1.7pp vs baseline). Worst draw at Romford. Vulnerable to trap 6 runners cutting in; requires exceptional closing pace. Avoid underlays in this trap.",
      "win_pct": 15,
      "running_style": "Wide runners / closers only",
      "rail_advantage": "Negative — wide runners at disadvantage"
    },
    {
      "trap": 6,
      "notes": "16% win rate (-0.7pp vs baseline). Outside draw avoids bend bunching and allows room to maneuver. Benefits strong wide-running specialists on this tight layout.",
      "win_pct": 16,
      "running_style": "Wide runners / outer-track specialists",
      "rail_advantage": "Neutral with strategic advantage in select races"
    }
  ],
  "grade_notes": "Trap bias is consistent across grades but most exploitable in lower-grade/maiden races where form variance is high and draw dominance is clearer.",
  "pace_profile": "Tight oval favors early pace and rail-hugging tactics. Front-runners from traps 1–2 set tempo and control bend entry. Closers face traffic and structural congestion.",
  "track_verdict": "Romford is one of the most draw-biased tracks in UK greyhound racing. Trap 1 is a genuine edge. Traps 1–2 dominate sprints. Trap 5 is systematically disadvantaged. Bettors should apply +3–5pp probability adjustment for trap 1 and avoid trap 5 underlays. For middle-distance races, draw bias remains but is less extreme than sprints. Apply form analysis rigorously, but overlay trap 1 when fundamentals align.",
  "betting_angles": [
    "Overvalue trap 1 runners in early-pace-dominant race profiles; apply +3–5% win probability uplift vs form alone.",
    "Trap 1–2 quinella/exacta combinations in sprints generate positive expectation vs crowd betting.",
    "Avoid trap 5 underlays; -1.7pp structural headwind requires exceptional form to overcome.",
    "Trap 6 wide runners suit strong, late-closing specialists who exploit outer-track room; pair with form advantage.",
    "In match races (trap 1 vs trap 5 same form), trap 1 carries intrinsic 5+ point probability edge.",
    "Lay trap 5 in any race without exceptional form justification; structural disadvantage + betting misprice = edge."
  ],
  "distance_notes": "Romford is a middle-distance (circa 500m typical) tight oval. Trap 1's advantage intensifies over shorter distances (sprint) due to bend compression; advantage normalizes slightly over longer distances (600m+) but remains pronounced.",
