In his favor / neutral
Nothing meaningful.
2 · Why — ranked hypotheses
No diagnostic pattern fires. Either the change is noise, or its cause sits in an unobserved layer (see data gaps).
3 · What the coach does tomorrow
Nothing — never fix what the data cannot show is broken.
Data gaps
- • Biomechanics (Hawkeye), TrackMan, and Blast Motion are team-internal — the mechanics layer is inferred from its downstream fingerprint, never observed.
