§ The result
Willo takes the total, Paycor takes more of the criteria.
Willo (Video interview) edges Paycor (ATS-integrated) by 1 point under rubric v1.0, 41 to 40. Paycor leads more of the criteria than Willo — 4 to 3 — but Bias Audit Transparency, which Willo leads, carries 18% of the rubric, and the weighted sum still falls to Willo. Bias Audit Transparency, at 18%, is the heaviest weighted swing and goes to Willo (Paycor 25, Willo 30), 41% of the weighted advantage it holds, while the widest raw gap is Human Oversight Design, Paycor 55 to Willo 62.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -1.2 — the difference between the two totals before either is rounded. Shares are of 3.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -1 beside that -1.2.

§ 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.
