§ The result
ZipRecruiter leads Arena Analytics by 8 points.
Under rubric v1.0, ZipRecruiter, filed under Sourcing, finishes on 40 and Arena Analytics, filed under Screening, on 32, 8 points apart. Arena Analytics takes 1 of the 7 criteria, Bias Audit Transparency among them, against 6 for ZipRecruiter, whose share includes Human Oversight Design. The advantage ZipRecruiter holds is spread out: Human Oversight Design is both the widest raw gap and the heaviest weighted swing (Arena Analytics 38, ZipRecruiter 55, 12% weight), yet it supplies only 24% of the weighted points ZipRecruiter gains across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -8.4 — the difference between the two totals before either is rounded. Shares are of 8.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -8 beside that -8.4.

§ 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.
