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

6 runners

Contested pace

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

2 E — pure early 1 EP — early/presser 1 P — presser 2 Unclassified

Projected speed

2 of 6 runners have no BRIS run-style code (often first-time starters); narrative may understate the true pace.

Trifecta shape

Tight

Highest hit-rate tier — best chance to cash a small ticket. Still negative-EV after takeout, but the model has a read.

  • · Most-likely-to-cash structure: 1×3×3 key (top pick) on posts [6, 2, 5, 3] — hits 18.8% of simulated runs
  • · At $6 stake, a typical cash pays ≈ $15 (mean $22; trifecta payoffs are heavy-tailed). Estimated from the public pool, validated against archive payoffs.
  • · Top 4 cover the ITM math — chalk should hit; payouts likely small.

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.
