New — Ask Claude Opus about this race Why a horse rates the way it does, what the trifecta ticket means, where the public might be wrong.

Pace shape

10 runners

Contested pace

4 early types — pace should be honest but not crazy. No strong style bias.

3 E — pure early 1 EP — early/presser 5 P — presser 1 S — closer

Projected speed

Trifecta shape

Wide open

Lottery shape — low hit rates, larger payouts when they cash. Entertainment-only; the model is not confident in any structure.

  • · Most-likely-to-cash structure: 1×3×3 key (top pick) on posts [8, 11, 10, 1] — hits 4.4% of simulated runs
  • · At $6 stake, a typical cash pays ≈ $29 (mean $48; trifecta payoffs are heavy-tailed). Estimated from the public pool, validated against archive payoffs.
  • · Wide-open shape — anyone could hit; longshots have room.

Hit prob is the model's per-race PL distribution. "Typical payout" is the median cash, weighted by the public pool's odds (not the model's own picks) and calibrated to actual historical trifecta payoffs — so it reflects what the tote really pays, not the model's disagreement. Walk-forward backtests show pari-mutuel takeout (~16-26%) is too steep to consistently clear at this data scale — these are tipsheet outputs, not bet recommendations.

Sort the table by clicking column headers. Edge = our predicted ITM% minus the public-implied ITM% (live odds when present, ML otherwise); green ▲ ≥ +5pp, red ▼ ≤ −5pp. Live column: ↓ green = ≥25% shorter than ML (money horse); ↑ red = ≥25% longer (drifting). See How to Use for the math.
