Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to -5.2 — the difference between the two totals before either is rounded. Shares are of 7.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -5 beside that -5.2.
