§ The result
Rezi leads Massive by 9 points.
Rezi scores 59 and Massive 50 under rubric js-v1.0, a 9-point gap across the Resume AI and Auto-apply cohorts. Rezi leads 6 of the 7 criteria, including Employer & ATS Legitimacy, while Massive leads 1, including Effectiveness Evidence. Employer & ATS Legitimacy is the widest raw gap and the heaviest weighted swing at once (Massive 40, Rezi 68, 15% weight), but it accounts for only 37% of the weighted advantage Rezi holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -8.7 — the difference between the two totals before either is rounded. Shares are of 14.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -9 beside that -8.7.

§ 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.
