§ The result
Willo takes the total, Pin takes more of the criteria.
Willo holds a 1-point edge over Pin under rubric v1.0, 41 to 40, across the Video interview and Sourcing cohorts. Pin leads more of the criteria, 4 against 3 for Willo, yet Willo takes Article 11 Technical Documentation, which carries 20% of the rubric, and the weighted sum with it. Willo takes the heaviest weighted swing, Article 11 Technical Documentation at 20% (Pin 30, Willo 38), which is 46% of the weighted advantage Willo holds; the widest raw gap is a different criterion, Human Oversight Design, Pin 50 to Willo 62.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -0.7 — the difference between the two totals before either is rounded. Shares are of 6.3 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 -0.7.

§ 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.
