§ The result
3 points separate SHL and ADP.
SHL (Assessment) edges ADP (ATS-integrated) by 3 points under rubric v1.0, 51 to 48. SHL leads 6 of the 7 criteria, including Article 11 Technical Documentation, while ADP leads 1, including Post-Market Monitoring. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — ADP 53, SHL 60 — and at a 20% weight it carries 45% of the weighted advantage SHL holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -2.5 — the difference between the two totals before either is rounded. Shares are of 3.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -3 beside that -2.5.

§ 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.
