1. Define the decision
Each study starts with a practical question, a US audience, a dated product set, explicit units, and criteria that can change the outcome.
2. Prefer primary sources
Manufacturer documentation, manuals, public authorities, and official carrier policies are preferred. Every unstable fact receives a verification date.
3. Calculate complete systems
When weight, compatibility, reach, power, or transport matters, Senkōra evaluates the complete usable kit rather than an isolated headline specification. Formulas and inclusions are stated beside the result.
4. Separate facts from judgment
Tables distinguish sourced values, calculations, and editorial conclusions. Missing or incomparable information remains visible rather than being estimated silently.
5. Publish limitations
Every study identifies what was not measured, what was not physically tested, regional constraints, and facts likely to change.
6. Maintain the work
Material changes trigger a new verification date and updates to every connected guide. Corrections follow the public corrections policy.
