Ranking by raw comfort% tied extreme places (Death Valley ranked #2 just
because 26% of days happened to land in-band). Replace it with a weighted
score that folds in tolerance days and miss magnitude, add an outer
tolerance range, and fix the Feels basis.
- Match score (0–100): each day scores full credit inside comfort [lo,hi],
partial credit inside the tolerance range (ramped 1→0 by how far past the
comfort edge it lands), zero beyond tolerance. Rank by the mean; tie-break
by smaller typical miss. Death Valley's hot days now score ~0 so it drops
to last. The score is the card's headline number.
- Tolerance range [tlo, thi] as an outer dual-thumb pair on the same track
(four handles, tlo ≤ lo ≤ hi ≤ thi), persisted + in the share hash.
Defaults to comfort widened 10° each side. The diverging bar now splits
each side into a within-tolerance band (lighter, near centre) and a
beyond-tolerance band (saturated), and the baseline strip shades the
tolerance range faintly around the comfort band.
- Feels basis now judges the felt daytime high (fmax) instead of the
combined `feels` metric, which reports whichever apparent extreme is
furthest from 65°F — in mild climates that flips to the cold overnight
low in winter and made comfortable days nearly vanish.
