How this week got its score
- 7 forecast days: 0 clear/mainly clear, 0 partly cloudy, 3 overcast, 3 wet (fog/drizzle/rain/showers), 1 stormy.
- Trimmed mean of day scores 5.5 × 0.55 = 3.04
- Worst day drag: worst day is 4.0 × 0.25 = 1.00 - one bad day cannot be averaged away.
- Longest consecutive run of good days (≥7.0) is 1/7 = 14% coverage × 0.20 = 0.29
- Best single day is 8.1 but it only counts through the trimmed mean - a lone great day cannot carry the window.
- Advertised 3-day window (2026-08-11→2026-08-13) scores 4.6 on its own.
- Legacy gate counted 4/7 days as "perfect sun"; this model counts 0 genuinely clear.
