§ The result
Factorial leads Paycor on 6 of the 7 criteria.
Factorial finishes 6 points ahead of Paycor under rubric v1.0, 46 to 40, both scored as ATS-integrated entries. Factorial leads 6 of the 7 criteria and the remaining criterion is level, so Paycor is ahead on none of them; the closest of the 6 Factorial leads is Human Oversight Design, Factorial 58 to Paycor 55. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Factorial 52, Paycor 40, 20% weight), but it accounts for only 36% of the weighted advantage Factorial holds across the 6 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 6 figures above sum to +6.6 — the difference between the two totals before either is rounded. Shares are of 6.6 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 +6.6.

§ 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.
