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

12 runners

Hot pace

5 early types pressing for the lead — expect a fast pace, favors closers (P/S).

4 E — pure early 1 EP — early/presser 2 P — presser 1 S — closer 4 Unclassified

Projected speed

4 of 12 runners have no BRIS run-style code (often first-time starters); narrative may understate the true pace.

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 [11, 1, 10, 5] — hits 1.2% of simulated runs
  • · At $6 stake, a typical cash pays ≈ $97 (mean $117; 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.
