§ The result
Plum takes the total, SHL takes more of the criteria.
Within the Assessment cohort, Plum edges SHL by 3 points under rubric v1.0, 54 to 51. SHL leads more of the criteria than Plum — 5 to 2 — but Bias Audit Transparency, which Plum leads, carries 18% of the rubric, and the weighted sum still falls to Plum. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Plum 83, SHL 50 — and at an 18% weight it carries 96% of the weighted advantage Plum holds across the 2 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +3.7 — 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 +3 beside that +3.7.

§ 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.
