Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +1.2 — the difference between the two totals before either is rounded. Shares are of 3.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +1 beside that +1.2.
