§ The result
Xobin leads Mercor on all 7 criteria.
Xobin (Assessment) and Mercor (Screening) are 27 points apart under rubric v1.0, 50 for Xobin against 23 for Mercor. Mercor leads none of the 7 criteria, and Xobin is ahead on 4 of them by 20 raw points or more, Article 11 Technical Documentation among them. The advantage Xobin holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Mercor 22, Xobin 62, 20% weight), yet it supplies only 29% of the weighted points Xobin gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -27.1 — the difference between the two totals before either is rounded. Shares are of 27.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -27 beside that -27.1.

§ 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.
