How Babylon.js’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 Score32/100

Agent-ready 51.4 × 0.30 = 15.42

API quality 20.6 × 0.20 = 4.12

Openness 54.0 × 0.20 = 10.80

Built-in AI 0.0 × 0.15 = 0.00

Automation 9.0 × 0.15 = 1.35

(15.42 + 4.12 + 10.80 + 0.00 + 1.35) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 31.69 ÷ 1.00 = 31.7

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.
