In April 2020, genomic lists promised a revolution in Holstein genetics. Five years later, 59% of those "elite" bulls never earned a daughter-proven proof, while Genosource Captain surged +369 TPI points and AOT Homecoming cratered -414. This episode tracks 401 bulls to December 2025, exposing why TPI volatility, base changes, and formula shifts crushed most — and handed massive gains to a few. If you're still betting heavy on young genomics without a proven anchor, here's the data to rethink your matings before the next proof run hits.

Key Takeaways:

• Why 59% of top genomic bulls vanished — and the biological vs. institutional reasons behind the attrition.
• The TPI "rollback": How the 2025 base change and feed efficiency formula erased 42.5 points on average — even from solid transmitters.
• Outliers ...
