§ The result
Checkr leads Willo on all 7 criteria.
Checkr sits 13 points above Willo under rubric v1.0 — 54 against 41 — with Checkr filed under Screening and Willo under Video interview. Checkr leads every one of the 7 criteria, Willo none of them, and the closest of the 7 is Human Oversight Design, Checkr 66 to Willo 62. Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing — Checkr 70, Willo 38 — and at a 20% weight it carries 49% of the weighted advantage Checkr holds across the 7 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +13.0 — the difference between the two totals before either is rounded. Shares are of 13.0 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 +13.0.

§ 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.
