§ The result
ADP leads Paycor on 6 of the 7 criteria.
Inside the ATS-integrated cohort, rubric v1.0 puts ADP on 48 and Paycor on 40, 8 points apart. ADP leads 6 of the 7 criteria and the remaining criterion is level, so Paycor is ahead on none of them; the closest of the 6 ADP leads is FRIA Support, ADP 28 to Paycor 27. One criterion, Bias Audit Transparency, is both the widest raw gap (ADP 46, Paycor 25) and the heaviest weighted swing, and at 18% weight it makes up 44% of the weighted advantage ADP holds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +8.7 — the difference between the two totals before either is rounded. Shares are of 8.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +8 beside that +8.7.

§ 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.
