§ The result
ADP leads Pin by 8 points.
Under rubric v1.0, ADP, filed under ATS-integrated, finishes on 48 and Pin, filed under Sourcing, on 40, 8 points apart. ADP leads 5 of the 7 criteria, including Article 11 Technical Documentation, while Pin leads 1, including FRIA Support, and 1 is level. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — ADP 53, Pin 30 — and at a 20% weight it carries 54% of the weighted advantage ADP holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +8.2 — the difference between the two totals before either is rounded. Shares are of 8.8 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 +8.2.

§ 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.
