Gappy seasons are excluded from the historical sample. We do not paint the zero-filled total as a poor / quiet percentile on the map.
Ghost lines are past seasons. Dashed is the median. Band is the 10th–90th percentile envelope. X-axis is day of season, not calendar year.
Sliding the date recomputes the percentile against the same calendar date in past seasons — never a full year vs a partial year.
