whole / plug = 1.0 — the baseline every published utilisation table was
measured against.
pellet = 1.10 — the widely used +10 % for the increased surface area of
milled, pelletised cones (Tinseth's own note; BeerSmith and Brewer's Friend
use the same figure).
co2-extract = 1.0 — pure resin already in solution, so the surface-area
reason for pellet's +10 % doesn't apply to it.
iso-extract = 1.0 — here so the record covers every form. It's never
read, because a pre-isomerised extract skips the utilisation model
(ibu.ts).
aroma-extract = 1.0 — has no effect, because these products have no
alpha acid and multiplying zero changes nothing.
cryo = 1.10 — a judgement call. Cryo/lupulin powder is a concentrated
pellet, and its extra bitterness is already in its (roughly doubled)
stated alpha-acid percentage. A second potency multiplier here would count
it twice, so cryo uses the pellet figure.
