Gem sits 13 points above Tengai under rubric v1.0 — 55 against 42 — with Gem filed under Sourcing and Tengai under Screening. Gem leads every one of the 7 criteria, Tengai none of them, and the closest of the 7 is Human Oversight Design, Gem 61 to Tengai 58.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +13.2 — the difference between the two totals before either is rounded. Shares are of 13.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +13 beside that +13.2.

§ 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.
