§ The result
4 points separate Pin and micro1.
Pin holds a 4-point edge over micro1 under rubric v1.0, 40 to 36, across the Sourcing and Screening cohorts. The 7 criteria split 6 to 1 in favour of Pin: Pin is ahead on Bias Audit Transparency and micro1 on Article 11 Technical Documentation. Article 11 Technical Documentation is at once the widest raw gap and the heaviest weighted swing, and it belongs to micro1 — micro1 50, Pin 30, on a 20% weight — which is 100% of the weighted advantage micro1 holds across the 1 criterion on that side of the table.
Vendor profile

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -4.1 — the difference between the two totals before either is rounded. Shares are of 12.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -4 beside that -4.1.

§ 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.
