§ The result
Textkernel leads Mercer | Mettl on 6 of the 7 criteria.
Textkernel scores 51 and Mercer | Mettl 42 under rubric v1.0, a 9-point gap across the Sourcing and Assessment cohorts. Textkernel leads 6 of the 7 criteria and the remaining criterion is level, so Mercer | Mettl is ahead on none of them; the closest of the 6 Textkernel leads is Post-Market Monitoring, Mercer | Mettl 38 to Textkernel 40. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Mercer | Mettl 38, Textkernel 55, 20% weight), but it accounts for only 37% of the weighted advantage Textkernel holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -9.2 — the difference between the two totals before either is rounded. Shares are of 9.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -9 beside that -9.2.

§ 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.
