§ The result
Dayforce leads Aon Assessment on all 7 criteria.
Dayforce finishes 22 points clear of Aon Assessment under rubric v1.0 — 57 against 35 — across the ATS-integrated and Assessment cohorts. Dayforce leads every one of the 7 criteria and 5 of them by 20 raw points or more, Article 11 Technical Documentation among them; Aon Assessment leads none. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Aon Assessment 40, Dayforce 74, 20% weight), but it accounts for only 31% of the weighted advantage Dayforce 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 -22.1 — the difference between the two totals before either is rounded. Shares are of 22.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -22 beside that -22.1.

§ 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.
