Methodology
How to read Arctavia’s public metrics.
Use the Iris Japan detail page to inspect the monthly table, comparison windows, sales definitions, and calculation conditions.
1. Fix the reporting scope
The Iris Japan monthly table sums cost and 30-day attributed sales by report date. Read monthly rows, rolling 30-day windows, and weekly charts as separate reporting periods.
2. Separate case studies from extra reference material
Public case studies such as Iris Japan stay distinct from additional packs used for sales or due diligence.
3. Check formulas and comparison windows
Recalculate ROAS as attributed sales / spend and ACoS as spend / attributed sales × 100. The window ending October 31, 2025 includes post-adoption days. Rounding and other changes mean the difference is not proof of a causal product effect.
Where to go next
Once the methodology is clear, the next useful step is moving between comparison pages and case studies without losing the proof path.
