Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +15.0 — the difference between the two totals before either is rounded. Shares are of 15.0 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 +15.0.

Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
