§ The result
HackerRank leads ADP by 7 points.
HackerRank scores 55 and ADP 48 under rubric v1.0, a 7-point gap across the Assessment and ATS-integrated cohorts. HackerRank leads 5 of the 7 criteria, including Bias Audit Transparency, while ADP leads 1, including Data Governance Disclosure, and 1 is level. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — ADP 46, HackerRank 68 — and at an 18% weight it carries 54% of the weighted advantage HackerRank holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -7.0 — the difference between the two totals before either is rounded. Shares are of 7.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -7 beside that -7.0.

§ 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.
