How Mercury Books’s scores are calculated

The full audit trail, recomputed from the verdict data at build time through the same code that produced the leaderboard: verdict × quality × story weight per cell, cells sum to dimension scores, dimensions blend into the PA Score. Every number on the product page is reproducible from this page alone; for why the formula looks like this, see the methodology.

verdict factors: full ×1.0 · partial ×0.6 · disputed ×0.3 · none ×0.0 · n/a excluded from both sides · cell points = weight × quality × factor · cell max = weight × 10

PA Score12/100

Agent-ready 0.6 × 0.30 = 0.18

API quality 0.0 × 0.20 = 0.00

Openness 0.0 × 0.20 = 0.00

Built-in AI 61.1 × 0.15 = 9.16

Automation 20.3 × 0.15 = 3.04

(0.18 + 0.00 + 0.00 + 9.16 + 3.04) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 12.39 ÷ 1.00 = 12.4

Scores are stored to 1 decimal; the product page’s pills round to whole numbers for display. Each dimension below shows the stories, verdicts, and cited evidence behind its number.
