§ The result
Dayforce leads Arena Analytics on all 7 criteria.
Rubric v1.0 puts 25 points between Dayforce (ATS-integrated) and Arena Analytics (Screening): 57 for Dayforce, 32 for Arena Analytics. Dayforce leads every one of the 7 criteria and 4 of them by 20 raw points or more, Article 11 Technical Documentation among them; Arena Analytics leads none. The advantage Dayforce holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Arena Analytics 30, Dayforce 74, 20% weight), yet it supplies only 34% of the weighted points Dayforce gains across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -25.7 — the difference between the two totals before either is rounded. Shares are of 25.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -25 beside that -25.7.

§ 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.
