Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -6.7 — 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 -7 beside that -6.7.
