§ The result
Bullhorn leads Knockri on 5 of the 7 criteria.
Bullhorn scores 54 and Knockri 47 under rubric v1.0, a 7-point gap across the ATS-integrated and Video interview cohorts. Bullhorn leads 5 of the 7 criteria and the remaining 2 are level, so Knockri is ahead on none of them; the closest of the 5 Bullhorn leads is FRIA Support, Bullhorn 38 to Knockri 35. One criterion, Bias Audit Transparency, is both the widest raw gap (Bullhorn 58, Knockri 35) and the heaviest weighted swing, and at 18% weight it makes up 58% of the weighted advantage Bullhorn holds across the 5 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +7.1 — the difference between the two totals before either is rounded. Shares are of 7.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +7 beside that +7.1.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
