§ The result
Retorio leads Arena Analytics on all 7 criteria.
Retorio, filed under Assessment, comes out 12 points above Arena Analytics, filed under Screening: 44 against 32 under rubric v1.0. Retorio takes all 7 criteria and Arena Analytics none of them; the nearest contest is FRIA Support, Arena Analytics 25 to Retorio 30. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Arena Analytics 30, Retorio 50, 20% weight), but it accounts for only 33% of the weighted advantage Retorio holds across the 7 criteria on that side of the table.

Shares are of 12.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -12 beside that -12.2.
