Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +2.5 — the difference between the two totals before either is rounded. Shares are of 5.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +3 beside that +2.5.
