According to the video (it’s elsewhere in the thread), the standard for uptime for industrial machinery is amazingly close to 100%. Given a million opportunities for such a machine to have a fault, you should want less than a handful of times that it actually craps itself.

McDonald’s machines are down more than 10% of the time.

If I was a big industrial conglomerate like GE, VDL or Samsung and I had a machine that was down 10% of the time, and the error reporting was opaque and forced me to call the manufacturer for a service technician, AND all the critical operating parameters are behind some special manual that only their service technicians are allowed to have, I’d fucking sue the manufacturer.
