§ The result
Spark Hire leads Arena Analytics on all 7 criteria.
Under rubric v1.0, Spark Hire (Video interview) opens a 21-point lead on Arena Analytics (Screening), 53 to 32. Arena Analytics leads none of the 7 criteria, and Spark Hire is ahead on 4 of them by 20 raw points or more, Bias Audit Transparency among them. Bias Audit Transparency is the widest raw gap and the heaviest weighted swing at once (Arena Analytics 25, Spark Hire 62, 18% weight), but it accounts for only 30% of the weighted advantage Spark Hire holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -21.9 — the difference between the two totals before either is rounded. Shares are of 21.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -21 beside that -21.9.
