No argument there.
But there's nothing entirely wrong with the PME quiz.
There's two sides to the pin as I see it:
The quals (eg OOD) reflect your ability to competently operate the platform at a minimum level.
The PME side reflects your ability to run the day to day operations. That is going to encompass both onboard PME outside your specialty (but affecting your watchstation quals) as well as the Ops type stuff that's needed to understand how the Ops world works for your unit. Because you can't just only do Eng stuff, you need to have some understanding of the programs outside your Department, or you'll be screwed in future assignments outside your previous "specialty."
Having said that, sure, some commands go way overboard with the PME stuff and go into the weeds on stupid shit that's of minimal relevance. And that's their fault.
