§ The result
impress.ai leads Mercor on all 7 criteria.
impress.ai finishes 15 points clear of Mercor inside the Screening cohort under rubric v1.0: 38 against 23. impress.ai leads every one of the 7 criteria, Mercor none of them, and the closest of the 7 is FRIA Support, impress.ai 25 to Mercor 20. Data Governance Disclosure is the widest raw gap and the heaviest weighted swing at once (impress.ai 55, Mercor 22, 15% weight), but it accounts for only 34% of the weighted advantage impress.ai holds across the 7 criteria on that side of the table.

Shares are of 14.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +15 beside that +14.5.

§ 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.
