§ The result
HeyMilo leads Plum on 5 of the 7 criteria.
HeyMilo scores 61 (D) and Plum 54 (F) under rubric v1.0, a 7-point gap across the Screening and Assessment cohorts. HeyMilo leads 5 of the 7 criteria and the remaining 2 are level, so Plum is ahead on none of them; the closest of the 5 HeyMilo leads is Customer Documentation, HeyMilo 66 to Plum 63. FRIA Support is the widest raw gap and the heaviest weighted swing at once (HeyMilo 42, Plum 28, 15% weight), but it accounts for only 34% of the weighted advantage HeyMilo holds across the 5 criteria on that side of the table.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +6.2 — the difference between the two totals before either is rounded. Shares are of 6.2 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +7 beside that +6.2.

§ 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.
