- Temperature: Scored against ideal activity range (18°C to 26°C). Deductions apply linearly outside this band.
- Wind: Up to 20 points deducted when peak gusts exceed 25 km/h.
- Time Zones: Hourly timestamps are evaluated against the target city’s native timezone (Europe/Athens) for daytime windows (07:00–22:00).
