A bespoke equine biomech model for buyers who measure before they bid.
Every claim verified, every number footnoted with sample size and p-value.
$100k the market's way → $52,200. Our way → $245,710. Within-band, tier-filtered (top biomech).
Top vs bottom biomech tercile. +86% in $0–50k, +71% in $100–200k.
15.1 vs 11.1 career starts at the same per-race ability. Top Biomech can 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.
Top Biomech has 8 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.
Every horse in the validation cohort, plotted on two of the biomech metrics that drive the score.
“Above $300k the model loses traction — the market is too inefficient 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.”
Briefings for bloodstock managers, syndicators and trainers. Eight Furlong is private and bespoke — we don't publish picks.
