§ The result
ADP leads impress.ai on 6 of the 7 criteria.
ADP sits 10 points above impress.ai under rubric v1.0 — 48 against 38 — with ADP filed under ATS-integrated and impress.ai under Screening. ADP leads 6 of the 7 criteria and the remaining criterion is level, so impress.ai is ahead on none of them; the closest of the 6 ADP leads is Data Governance Disclosure, ADP 57 to impress.ai 55. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — ADP 46, impress.ai 22 — and at an 18% weight it carries 41% of the weighted advantage ADP holds across the 6 criteria on that side of the table.

Shares are of 10.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +10 beside that +10.6.

§ 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.
