§ The result
3 points separate Paradox and impress.ai.
Paradox (Scheduling) edges impress.ai (Screening) by 3 points under rubric v1.0, 41 to 38. impress.ai and Paradox each lead 3 of the 7 criteria, with 1 level, though the side of the split Paradox holds (headed by Bias Audit Transparency) adds up to more weighted points. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — impress.ai 22, Paradox 50 — and at an 18% weight it carries 79% of the weighted advantage Paradox holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -3.6 — the difference between the two totals before either is rounded. Shares are of 9.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -3 beside that -3.6.

§ 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.
