How Loops’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 Score34/100
Agent-ready 60.1 × 0.30 = 18.03
API quality 37.7 × 0.20 = 7.54
Openness 10.3 × 0.20 = 2.06
Built-in AI 21.3 × 0.15 = 3.19
Automation 19.5 × 0.15 = 2.92
(18.03 + 7.54 + 2.06 + 3.19 + 2.92) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 33.75 ÷ 1.00 = 33.8
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.
