Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +0.5 — the difference between the two totals before either is rounded. Shares are of 4.4 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads 0 beside that +0.5.
