§ The result
Paradox leads Arena Analytics on 6 of the 7 criteria.
Paradox scores 41 and Arena Analytics 32 under rubric v1.0, a 9-point gap across the Scheduling and Screening cohorts. Paradox leads 6 of the 7 criteria and the remaining criterion is level, so Arena Analytics is ahead on none of them; the closest of the 6 Paradox leads is Data Governance Disclosure, Arena Analytics 42 to Paradox 45. One criterion, Bias Audit Transparency, is both the widest raw gap (Arena Analytics 25, Paradox 50) and the heaviest weighted swing, and at 18% weight it makes up 46% of the weighted advantage Paradox holds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -9.8 — the difference between the two totals before either is rounded. Shares are of 9.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -9 beside that -9.8.

§ 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.
