Eightfold AI finishes 16 points clear of ADP under rubric v1.0 — 64 (D) against 48 (F) — across the Sourcing and ATS-integrated cohorts. Eightfold AI leads every one of the 7 criteria, ADP none of them, and the closest of the 7 is Customer Documentation, ADP 58 to Eightfold AI 60. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — ADP 46, Eightfold AI 85 — and at an 18% weight it carries 44% of the weighted advantage Eightfold AI holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -15.8 — the difference between the two totals before either is rounded. Shares are of 15.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -16 beside that -15.8.

§ 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.
