§ The result
Aon Assessment leads XOR by 5 points.
Aon Assessment scores 35 and XOR 30 under rubric v1.0, a 5-point gap across the Assessment and Screening cohorts. Aon Assessment leads 3 of the 7 criteria, including Article 11 Technical Documentation, while XOR leads 2, including Post-Market Monitoring, and 2 are level. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Aon Assessment 40, XOR 20 — and at a 20% weight it carries 59% of the weighted advantage Aon Assessment holds across the 3 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +5.2 — the difference between the two totals before either is rounded. Shares are of 8.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +5 beside that +5.2.

§ 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.
