Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +5.6 — the difference between the two totals before either is rounded. Shares are of 5.8 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 +5.6.
