Eternity Summer 2017 against Eternity Summer 2020
One number per era rather than one number overall — two fragrances can be
near-identical at the opening and different things by the evening, and an
average hides exactly that.
How close, and when
Across a whole wearing, Calvin Klein Eternity Summer 2017 and Calvin Klein Eternity Summer 2020 are distantly related. They are nearest during the drydown and furthest apart in the opening, which is the part a single figure would average away.
33%
opening · 0–1 h
39%
heart · 1–3 h
62%
drydown · 3–8 h

- At the heart, 1 to 3 hours in, the two are distantly related.
- At the drydown, 3 to 8 hours in, the two are related, not interchangeable.
Measured across all twenty-four facets, from the notes below — not from the
families on the boxes. They share
3 of 15 materials, which is
worth holding beside the figures: a pair can share almost nothing and still
converge, because different materials can smell of the same things.
What AKIN predicts
AKIN predicts these two are alike, and the evidence behind that is substantial.
Two signals sit on this page and are never averaged: what the note
pyramids measure these two to share, and what AKIN’s resemblance
graph predicts. Where they part, that is the finding rather than a fault.
The pyramids, side by side
Compared by material rather than by spelling, so a note recorded two ways is
not counted as a difference.
