Just took a pci/psi visual course. Looking for more precise information

You should have taken the class from Mark, the owner. Then you could have spent at least an hour of that time learning about how many astronauts he knows and why he is smarter than any of them.

I did take my second class from Mark, and IIRC, he was too exuberant to limit it to an hour.

Mine was with Mark about 9 yrs ago (2007?). We spent an insane amount of time on 6351 cylinders - all of which was useless parroting of CGA-DOT lobbying points on why 6351 cylinders are "safe" (zero recognition that safe is in the eye of the beholder).

Nothing on astronauts that I recall, also nothing on steel cylinders worth remembering. Although I do recall I was supposed to "renew" my industry leading credentials with them many years ago. That was repeated many times.
