How Vercel’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 Score25/100
Agent-ready 43.7 × 0.30 = 13.11
API quality 21.6 × 0.20 = 4.32
Openness 8.4 × 0.20 = 1.68
Built-in AI 20.0 × 0.15 = 3.00
Automation 21.0 × 0.15 = 3.15
(13.11 + 4.32 + 1.68 + 3.00 + 3.15) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 25.26 ÷ 1.00 = 25.3
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.
