Before you rely on this

BASS-II lowered the oxygen and never raised it above 22.2%, so a Moon habitat's air cannot be set here: no solid was burned in it. How each test ended was read from NASA's own table and report by an SI tool; no person has checked those readings yet. One step is 1 point of oxygen, or 5 cm/s of air speed, or a 25% change in size: tests within one step count as measured here, within two as close.
