§ The result
Wellfound takes the total, ADP takes more of the criteria.
Wellfound (Screening) edges ADP (ATS-integrated) by 4 points under rubric v1.0, 52 to 48. ADP leads more of the criteria than Wellfound — 3 to 2 — but Bias Audit Transparency, which Wellfound leads, carries 18% of the rubric, and the weighted sum still falls to Wellfound. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — ADP 46, Wellfound 82 — and at an 18% weight it carries 78% of the weighted advantage Wellfound holds across the 2 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to -3.5 — the difference between the two totals before either is rounded. Shares are of 13.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -4 beside that -3.5.

Raw score per criterion, with weighted delta.

§ 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.
