§ The result
Saville Assessment leads Aon Assessment on all 7 criteria.
Both filed under Assessment, Saville Assessment and Aon Assessment come out 48 and 35 under rubric v1.0, 13 points in favour of Saville Assessment. Saville Assessment takes all 7 criteria from Aon Assessment without a 20-point raw gap on any of them; the closest is Article 11 Technical Documentation, Aon Assessment 40 to Saville Assessment 50. Data Governance Disclosure is the widest raw gap and the heaviest weighted swing at once (Aon Assessment 38, Saville Assessment 55, 15% weight), but it accounts for only 20% of the weighted advantage Saville Assessment holds across the 7 criteria on that side of the table.

Shares are of 12.7 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -13 beside that -12.7.
