I don't believe they ever ran at 16 psi gage. The capsule was designed to run pure oxygen at the same partial pressure as on earth, which meant around 3 psi, absolute in space. I believe the tests were run at 3 psi over atmospheric, or about 17.7 or so absoute.
Would not 30 psi absolute of oxygen be deadly?
