§ The result
Checkr and Plum tie at 54.
Checkr (Screening) and Plum (Assessment) tie at 54 under rubric v1.0, arriving there from different criteria. Checkr leads 6 of the 7 criteria and Plum 1, yet the two totals land on the same number. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Checkr 35, Plum 83 — and at an 18% weight it carries 100% of the weighted advantage Plum holds across the 1 criterion on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -0.7 — the difference between the two totals before either is rounded. Shares are of 16.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads 0 beside that -0.7.

§ 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.
