Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +3.3 — the difference between the two totals before either is rounded. Shares are of 8.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +4 beside that +3.3.
