§ The result
DevSkiller leads Mercor on all 7 criteria.
DevSkiller finishes 16 points clear of Mercor under rubric v1.0 — 39 against 23 — across the Assessment and Screening cohorts. DevSkiller leads every one of the 7 criteria, Mercor none of them, and the closest of the 7 is FRIA Support, DevSkiller 25 to Mercor 20. Data Governance Disclosure is the widest raw gap and the heaviest weighted swing at once (DevSkiller 52, Mercor 22, 15% weight), but it accounts for only 29% of the weighted advantage DevSkiller 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 +15.4 — the difference between the two totals before either is rounded. Shares are of 15.4 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 +15.4.

§ 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.
