§ The result
Fuel50 leads Paradox on all 7 criteria.
Under rubric v1.0, Fuel50 (Sourcing) opens a 17-point lead on Paradox (Scheduling), 58 to 41. Of the 7 criteria Paradox wins none, and the narrowest lead Fuel50 holds is on Post-Market Monitoring, Fuel50 40 to Paradox 35. Even Article 11 Technical Documentation, the widest raw gap and the heaviest weighted swing (Fuel50 70, Paradox 40, 20% weight), is only 37% of the weighted advantage Fuel50 builds across the 7 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +16.4 — the difference between the two totals before either is rounded. Shares are of 16.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +17 beside that +16.4.

§ 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.
