Yeah, those new sensors are shockingly good at ignoring normal noise (like, way better than the old ones).

Except labor costs were way lower back then.

Ever notice how that happens with all kinds of progress? You hit what looks like a solid win, but it actually means you're in for a harder, slower grind. It's like finally getting the old engine apart only to find the real rust problem is deeper inside. That cheer for hitting rock is the same feeling, but the person who knows the job sees the coming trouble. Makes you wonder how often we celebrate the wrong thing, doesn't it?
