Alpha to beta runs about 2.4:1, which is what governs how fast the bitterness fades in storage.
Oil composition
Not enough of this hop's oil is accounted for to show a breakdown. The sources on file name components totalling 0.9% of total oil — most of the balance is myrcene, which the source for this record doesn't publish. Rather than scale what's here up to 100% and invent the rest, here is only what was actually measured:

What to swap it for
Scored on aroma overlap, oil composition and acid chemistry, then nudged up where a brewer has vouched for the swap by hand. An axis we haven't measured earns nothing, so a hop known only by its acid numbers caps out around 30 — the score is how much evidence there is for the swap, not just how close the numbers happen to be. Anything under 50 is a different beer, not a substitution.
