Learned not to be cheap
Over the winter i do some major service of my bike. I checked the chain, with the Park tool, and it was under .5% wear so I reinstalled it. I've put about 500 miles on it since and a few days ago it would occasionally jump a tooth in the 4th and 5th largest cog. It was suggested that maybe it was a tight link so i checked the chain and didn't find any. So at my son's suggestion I changed the chain and .... not only is the problem resolved, it shifts so much smoother.
I'm glad that my LBS not only had it in stock, they also have a decent online presence and I got it for the online price... $45 for a Sram Red 22 chain.
I'm just going to replace the chain every winter, even if the Park tool says it's under the .5% mark.
BTW, i hung both chains from a finish nail in a ceiling joist to get the correct length to cut and the old chain was 1/3 of a link longer.

I think the Park tool is inaccurate at times and for the price I just change my chains proactively as well.

The ruler is truth.

Whatever the word is, it seems like the Park tool, which I also have, isn't as reliable as good-old measuring the chain with a tape measure. From center of rivet to center of rivet should be 12 inches for 12 full links. I prefer to change it out at 1/16" of elongation.

I replace the entire drivetrain, that being the chainrings, cassette and chain at the same time. They all work and wear as a unit and replacing only one worn item will cause the new one to prematurely wear.

It's better to replace the chain more frequently. Shifting will be better and your cassette should last at least 3 chains. Chainrings last much longer.

My chain rings outlast at least 4 or 5 cassettes, each of which last for about 3 chains. And I let them get closer to 1/8" than 1/16. As I figure it, my chain ring lasts more than 15 times as long as someone who replaces everything at once.

I use a tape measure. Why buy "Park" when unnecessary? And just because it has a blue handle it doesnt mean it's the best.
Do you want accurate? Start with a 6" dial caliper. If you keep the chains fairly fresh through the seasons you wont need to replace FW/Cassette/Chainrings as much.

There is no need to measure the chain length if you replace it every year . My Campagnolo Chorus chain costs $40.0 from UK retailers . Indeed , why go cheap on it when you don't have to at this price . I also replace the whole cassette after 3 chains .

Coincidentally I was thinking it's new chain time on Wednesday's ride. I can hear the chain just a bit recently, especially when it's in any gear combo that presents a slight angle. Not bad, just not silent anymore.
Checked my ride data, looks like 1,500 miles since my last chain replacement back in the late fall/early winter.
Seems a bit early but I do ride gravel and gritty chip seal and rural routes about half the time, so maybe 1,500 miles is reasonable for that mix.
My '92 bike has an older but still replaceable Shimano Hyperglide cassette, so I'm not too worried about that. But the triple chain ring is an Exage aluminum 30/40/50. Probably harder to find and more expensive. Better to replace the chain earlier.
