Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +9.5 — the difference between the two totals before either is rounded. Shares are of 11.0 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +9 beside that +9.5.
