First Season

Top, heart and base are the pyramid as published, not a timing claim. Each note's timing follows its listed tier, where it usually sits across many published pyramids (from ScentPrism) and its vapour pressure. A note comes through as the notes usually listed before it fade, judged from how other pyramids order the same pair. The thickness of a ribbon shows the note's share of what is left on the skin, which tracks how strongly it smells, because odour thresholds rise with vapour pressure. The shares come from how prominent wearers vote each note. It is a simple model, not a measurement.
