F2 — GPM per Traffic Source

Why there's no absolute USD/IDR figure by source: Feed 4 explicitly states SHARES ONLY — Σ GMV by source can exceed room GMV due to overlap attribution (quirk Q4, metric_definitions.md). The table below only uses traffic share % and GPM index relative to the room baseline. The source "others" is permanently excluded from the table (2026-07-19 decision) but still counts toward the baseline denominator, so it doesn't shrink other sources' index.
