§ The result
ADP leads Zappyhire on all 7 criteria.
ADP sits 14 points above Zappyhire under rubric v1.0 — 48 against 34 — with ADP filed under ATS-integrated and Zappyhire under Screening. ADP leads every one of the 7 criteria, Zappyhire none of them, and the closest of the 7 is FRIA Support, ADP 28 to Zappyhire 25. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (ADP 53, Zappyhire 30, 20% weight), but it accounts for only 32% of the weighted advantage ADP 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 +14.2 — the difference between the two totals before either is rounded. Shares are of 14.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +14 beside that +14.2.

§ 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.
