Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +15.5 — the difference between the two totals before either is rounded. Shares are of 15.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +15 beside that +15.5.
