Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +22.4 — the difference between the two totals before either is rounded. Shares are of 22.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +23 beside that +22.4.

§ Evidence
Cited sources and documented absences, criterion by criterion.
