§ The result
Plum takes the total, Employment Hero takes more of the criteria.
Plum scores 54 and Employment Hero 48 under rubric v1.0, a 6-point gap across the Assessment and Screening cohorts. Employment Hero leads more of the criteria than Plum — 4 to 3 — but Bias Audit Transparency, which Plum leads, carries 18% of the rubric, and the weighted sum still falls to Plum. One criterion, Bias Audit Transparency, is both the widest raw gap (Employment Hero 35, Plum 83) and the heaviest weighted swing, and at 18% weight it makes up 84% of the weighted advantage Plum holds across the 3 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -6.5 — the difference between the two totals before either is rounded. Shares are of 14.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -6 beside that -6.5.

§ 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.
