§ The result
Pin leads Arena Analytics on 6 of the 7 criteria.
Pin scores 40 and Arena Analytics 32 under rubric v1.0, an 8-point gap across the Sourcing and Screening cohorts. Pin leads 6 of the 7 criteria and the remaining criterion is level, so Arena Analytics is ahead on none of them; the closest of the 6 Pin leads is FRIA Support, Arena Analytics 25 to Pin 30. Even Post-Market Monitoring, the widest raw gap and the heaviest weighted swing (Arena Analytics 28, Pin 45, 12% weight), is only 24% of the weighted advantage Pin builds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -8.6 — the difference between the two totals before either is rounded. Shares are of 8.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -8 beside that -8.6.

§ 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.
