Facet averages, against the whole catalog

|---|---|---|---|---|
| Developer Ergonomics | 39.2 | 17.9 | +21.3 | 51 |

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
