§ The result
Phenom leads Paradox by 11 points.
Phenom sits 11 points above Paradox under rubric v1.0 — 52 against 41 — with Phenom filed under Sourcing and Paradox under Scheduling. Phenom leads 5 of the 7 criteria, including Bias Audit Transparency, while Paradox leads 1, including Post-Market Monitoring, and 1 is level.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -11.2 — the difference between the two totals before either is rounded. Shares are of 12.3 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -11 beside that -11.2.

§ 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.
