I can guarantee that both those MMs lost a rate or 2. I lost one for doing
preventative maintenance on a valve (cycling it open/close in this case).
The problem was I did it from the remote (think wrench extension). Although
I could see the valve stem actually turning through the grate, an E7 ET had
me go before the Captain (Article 15).
