Bullhorn sits 10 points above Retorio under rubric v1.0 — 54 against 44 — with Bullhorn filed under ATS-integrated and Retorio under Assessment. Bullhorn is ahead of Retorio on all 7 criteria but on none of them by as much as 20 raw points, the closest being Post-Market Monitoring at Bullhorn 35 to Retorio 33.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +10.0 — the difference between the two totals before either is rounded. Shares are of 10.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +10 beside that +10.0.

§ 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.
