i'm pretty sure it was sivetz, by comparative cupping of coffee stored
in various O2 concentrations over time.

iirc, "1%" means one percent of free atmospheric O2, or an O2 level of
..21% of package contents (assuming 21% O2 in "normal" air), or an
equivalence of 29.608 in-Hg vacuum. a thorough N2 flush should negate
the need to vac pack.
