§ The result
Mercer | Mettl leads Turing by 6 points.
Mercer | Mettl scores 42 and Turing 36 under rubric v1.0 — a 6-point gap inside the Assessment cohort. Mercer | Mettl leads 5 of the 7 criteria, including Bias Audit Transparency, while Turing leads 1, including Article 11 Technical Documentation, and 1 is level. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Mercer | Mettl 42, Turing 28 — and at an 18% weight it carries 40% of the weighted advantage Mercer | Mettl holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +5.5 — the difference between the two totals before either is rounded. Shares are of 7.1 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 +5.5.

§ 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.
