Tiny, weird parade" is a bit much, Derek656. It's just some old junk in a pipe. I've pulled out way worse than bath toys (think a full, furry possum once). A line of ducks is just weird clutter, not some big mystery.

But pennies add up across a dozen devices, don't they?

That "empty car" thing is just one tiny example of how much we all rely on invisible social rules.

Yeah, that number hits close to home. We spend a stupid amount of time just hauling stuff from point A to B. My crew started doing a five minute huddle to plan material placement, and it actually shaved a good chunk of that wasted time off our day.

Honestly that's a bit low for what I've seen, @wilson.sam. A really clogged filter can drop airflow way more than that, especially in older units. It's one of those simple things that makes a huge difference.
