$100k the market's way → $52,200. Our way → $245,710. Within-band, tier-filtered (sub-$50k × top biomech).
Same-band coin-flip: top vs bottom biomech tercile. +86% in $0–50k, +71% in $100–200k. Survives a 5% outlier trim.
15.1 vs 11.1 career starts at the same per-race ability. They race more often — and longer.
13.8% vs 4.6%. Triple the chance a horse is still on the track when the deep career money is paid.
Eight more percentage points of multi-race winners. Not flukes — repeat winners.
PM-per-dollar lift holds steady across seven yearling vintages. Not a single-year anomaly.
The signal is rare on purpose. Net +8 = top 2% / 1 in 48. Few horses clear it — and that's the point.
Works on both sides of the catalogue. Sex-consistent — not a fluke of one population.
“Above $300k the model adds nothing — the market is too distorted at the prestige end. For the 72% of yearlings that sell below that ceiling — where 7 out of 10 bids land — we're 60–86% better than chance.”
