micro1 holds a 1-point edge over Aon Assessment under rubric v1.0, 36 to 35, across the Screening and Assessment cohorts. The criteria split evenly, 3 each to Aon Assessment and micro1, with 1 level, and the weighted points on the side micro1 holds, headed by Article 11 Technical Documentation, settle the total.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -0.9 — the difference between the two totals before either is rounded. Shares are of 5.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -1 beside that -0.9.

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.
