§ The result
Bullhorn leads Paradox on 6 of the 7 criteria.
Bullhorn sits 13 points above Paradox under rubric v1.0 — 54 against 41 — with Bullhorn filed under ATS-integrated and Paradox under Scheduling. Bullhorn leads 6 of the 7 criteria and the remaining criterion is level, so Paradox is ahead on none of them; the closest of the 6 Bullhorn leads is Bias Audit Transparency, Bullhorn 58 to Paradox 50. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Bullhorn 62, Paradox 40, 20% weight), but it accounts for only 35% of the weighted advantage Bullhorn holds across the 6 criteria on that side of the table.

1.2 weighted points to Bullhorn
Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +12.4 — the difference between the two totals before either is rounded. Shares are of 12.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +13 beside that +12.4.

§ 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.
