That needle wiggle @violay27 mentioned is a feature, not a bug. It's how the gauge tells you it's seen some things. Had a similar thing with a factory Honda clearcoat reading way thin last year. The spec was fine, but the old gauge just kept shivering on the low end. Ended up doing a test spot with a slower reducer, and sure enough, the factory must have had a bad day. Sometimes the new tech just sees the number it expects to see.

It's funny how often people ditch the basics once new tools show up. Saw the same thing with painters skipping primer because "paint and primer in one" exists, then wondering why their walls look bad in a year. The old ways stick around because they work, even if they're a pain.

Oh man, I read a study once that said most accidents happen during routine moves, not the tricky ones. That eye contact rule is key.

Honestly, that's so true. It feels like their main job is just to be the person you're allowed to be mad at when the whole system is broken.

Tell me about it, my desk looks like a spider built a web out of charging cables.
