How this week got its score
- 7 forecast days: 0 clear/mainly clear, 0 partly cloudy, 5 overcast, 2 wet (fog/drizzle/rain/showers), 0 stormy.
- Trimmed mean of day scores 6.3 × 0.55 = 3.48
- Worst day drag: worst day is 5.4 × 0.25 = 1.35 - 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 7.2 but it only counts through the trimmed mean - a lone great day cannot carry the window.
- Advertised 3-day window (2026-08-06→2026-08-08) scores 6.1 on its own.
- Legacy gate counted 7/7 days as "perfect sun"; this model counts 0 genuinely clear.
