§ The result
Wellfound takes the total, Factorial takes more of the criteria.
Wellfound scores 52 and Factorial 46 under rubric v1.0, a 6-point gap across the Screening and ATS-integrated cohorts. Factorial leads more of the criteria than Wellfound — 5 to 2 — but Bias Audit Transparency, which Wellfound leads, carries 18% of the rubric, and the weighted sum still falls to Wellfound. One criterion, Bias Audit Transparency, is both the widest raw gap (Factorial 25, Wellfound 82) and the heaviest weighted swing, and at 18% weight it makes up 88% of the weighted advantage Wellfound holds across the 2 criteria it leads.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -5.6 — the difference between the two totals before either is rounded. Shares are of 17.8 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -6 beside that -5.6.

§ 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.
