§ The result
ZipRecruiter leads Mercor on all 7 criteria.
Under rubric v1.0, ZipRecruiter (Sourcing) opens a 17-point lead on Mercor (Screening), 40 to 23. Of the 7 criteria Mercor wins none, and the narrowest lead ZipRecruiter holds is on FRIA Support, Mercor 20 to ZipRecruiter 27. The advantage ZipRecruiter holds is spread out: Data Governance Disclosure is both the widest raw gap and the heaviest weighted swing (Mercor 22, ZipRecruiter 52, 15% weight), yet it supplies only 27% of the weighted points ZipRecruiter gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -16.8 — the difference between the two totals before either is rounded. Shares are of 16.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -17 beside that -16.8.

§ 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.
