Plum leads TestDome on 5 of the 7 criteria.
Plum finishes 17 points clear of TestDome inside the Assessment cohort under rubric v1.0: 54 against 37. Plum leads 5 of the 7 criteria and the remaining 2 are level, so TestDome is ahead on none of them; the closest of the 5 Plum leads is Customer Documentation, Plum 63 to TestDome 60. One criterion, Bias Audit Transparency, is both the widest raw gap (Plum 83, TestDome 15) and the heaviest weighted swing, and at 18% weight it makes up 70% of the weighted advantage Plum holds across the 5 criteria it leads.

Shares are of 17.4 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 +17.4.

§ 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.
