§ The result
Eightfold AI leads Plum by 10 points.
Eightfold AI sits 10 points above Plum under rubric v1.0 — 64 (D) against 54 (F) — with Eightfold AI filed under Sourcing and Plum under Assessment. Eightfold AI leads 6 of the 7 criteria, including Article 11 Technical Documentation, while Plum leads 1, including Customer Documentation.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +9.6 — the difference between the two totals before either is rounded. Shares are of 10.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +10 beside that +9.6.
