§ The result
micro1 leads Mercor on all 7 criteria.
micro1 sits 13 points above Mercor under rubric v1.0, 36 against 23, with both filed under Screening. micro1 leads every one of the 7 criteria, Mercor none of them, and the closest of the 7 is FRIA Support, Mercor 20 to micro1 22.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to -12.9 — the difference between the two totals before either is rounded. Shares are of 12.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads -13 beside that -12.9.

§ 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.
