§ The result
Korn Ferry takes the total, Willo takes more of the criteria.
Korn Ferry scores 46 and Willo 41 under rubric v1.0, a 5-point gap across the Assessment and Video interview cohorts. Willo leads more of the criteria than Korn Ferry — 4 to 2 — but Article 11 Technical Documentation, which Korn Ferry leads, carries 20% of the rubric, and the weighted sum still falls to Korn Ferry. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Korn Ferry 58, Willo 38 — and at a 20% weight it carries 55% of the weighted advantage Korn Ferry holds across the 2 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +5.4 — the difference between the two totals before either is rounded. Shares are of 9.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +5 beside that +5.4.

§ 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.
