When he gets hit
how often Chuck Campbell fires back within 2 seconds of eating a strike. The “vs chance” number compares that to what his own pace would produce at random — so it measures deliberate answering, not just busyness. This is about his offense, not how open he is to being hit.
When strikes come at Campbell, he fires back within 2 seconds 13% of the time. That's 1.1× what his own pace would produce by chance.

Verified verdict profile
Operator verdict-ledger evidence, kept separate from temporal tendencies. Complete reviews may support totals and gated rates; partial reviews remain labeled samples; reviews below the coverage floor expose only their withholding reason.
The three frozen verdict gates
- Per-fight mix shares require n ≥ 25 reviewed real attempts; below it, counts only.
- Complete-fight pooled mix shares and own rates require n ≥ 25 real attempts.
- Defense clean-absorb rates require a complete review and n ≥ 25 opponent real attempts.
- Partial reviews are non-random samples: counts and eligible sample mixes are not fight totals or accuracy.
- Physical side means left/right, not lead/rear stance. Jab/cross for swept strikes is stance-INFERRED from pose: a windowed ankle-vote at the strike instant when decisive (94.3% vs hand-log truth), else the fight-level lead; strikes where both abstain stay "straight" rather than guess.
- A single reviewer produced these verdicts; unresolved attribution/validity verdicts are a floor on missingness.
Coverage & provenance
adjudication_only
Not measurable from broadcast
the single-feed footage can’t support these — they are not a locked upgrade, they simply aren’t recoverable. Saying so is the product.
Landed / grazed / missed
outcome carries ~no machine signal at this capture and is unreliable even by eye from a single broadcast feed
Fine punch subtype (jab / cross / hook)
capped by 72% annotator self-agreement and the single-feed capture wall
Clinch & ground interior
the corpus is standup-scoped — a single broadcast feed can't resolve grappling exchanges
Feint intent
intent-without-contact is not recoverable from broadcast video
Known limits
- single-annotator ground truth; measured undercount ~8.8% on the deepest-swept fight — global estimate 11–15%; every count is a floor, not an exaggeration
- tendency numbers are standup-scoped and in-round; clinch/ground exchanges are not measured
- stance (lead/rear) is a per-fight constant from a pose asset; a mid-fight stance switch would mislabel lead/rear symmetrically
- per-round counts sit on a Poisson floor of roughly ±18–25%; product language is trends and conditionals, never single-round precision
