Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -23.7 — the difference between the two totals before either is rounded. Shares are of 23.7 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 -23.7.
