§ The result
Knockri leads Arena Analytics on all 7 criteria.
Knockri finishes 15 points clear of Arena Analytics under rubric v1.0 — 47 against 32 — across the Video interview and Screening cohorts. Knockri leads every one of the 7 criteria, Arena Analytics none of them, and the closest of the 7 is Post-Market Monitoring, Arena Analytics 28 to Knockri 35. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Arena Analytics 30, Knockri 55, 20% weight), but it accounts for only 33% of the weighted advantage Knockri holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -15.1 — the difference between the two totals before either is rounded. Shares are of 15.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -15 beside that -15.1.

§ 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.
