§ The result
Paycom leads Mercor on all 7 criteria.
Rubric v1.0 puts 27 points between Paycom (ATS-integrated) and Mercor (Screening): 50 for Paycom, 23 for Mercor. Paycom leads every one of the 7 criteria and 4 of them by 20 raw points or more, Article 11 Technical Documentation among them; Mercor leads none. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Mercor 22, Paycom 68, 20% weight), but it accounts for only 34% of the weighted advantage Paycom 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 -27.1 — the difference between the two totals before either is rounded. Shares are of 27.1 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -27 beside that -27.1.

§ 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.
