§ The result
Testlify leads DevSkiller on 6 of the 7 criteria.
Inside the Assessment cohort, rubric v1.0 puts Testlify on 45 and DevSkiller on 39, 6 points apart. Testlify leads 6 of the 7 criteria and the remaining criterion is level, so DevSkiller is ahead on none of them; the closest of the 6 Testlify leads is Post-Market Monitoring, DevSkiller 40 to Testlify 42. One criterion, Article 11 Technical Documentation, is both the widest raw gap (DevSkiller 35, Testlify 52) and the heaviest weighted swing, and at 20% weight it makes up 49% of the weighted advantage Testlify holds across the 6 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -6.9 — the difference between the two totals before either is rounded. Shares are of 6.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -6 beside that -6.9.

§ 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.
