Calling it 'too simple' is right on point. I found that just moving stuff around wasn't enough, so I added in some neck exercises every morning. That made a real difference over time.

Your plastic sheeting trick is GENIUS. My friend learned the hard way when he ignored a moisture check on a garage conversion. The adhesive failed after two months, peeling up all the luxury plank. He lost money and a client. Now he uses that exact method before every single install.

Weird, I used to think those stories were fake.

Funny how the old ways stick with you. I still chalk a line next to the digital readout, a quick visual check that's saved my butt more than once when a sensor got fussy. Teach the new guys to run the scanner, but make them check the first plate with a level and feeler gauges too. That way they learn what "right" feels like, not just what the screen says. What's one old-school check you still do out of habit?

Wait, it's not just the bad calls though, is it? That stuff happens. What really kills morale is when they never listen to why it was a bad call, or just act like it didn't happen. The silence after a mistake is way worse than the mistake itself.
