How to approach the decision
Editorial planning advice based on the confirmed systems above.
- Use consistent conditions when comparing screenshots or visibility.
- Treat timetable or time-of-day demand effects as unverified unless official evidence establishes them.
A mistake to avoid
Do not turn a visual night cycle into an invented night-time passenger formula.
What still needs live data
Any simulation effect beyond the described presentation controls.
We will update this guide before opening individual database records. Unverified shells are excluded from search and the sitemap.
