Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -21.0 — the difference between the two totals before either is rounded. Shares are of 21.3 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 -21.0.
