Tried a Park Tool chain checker instead of my ruler method and got a different answer on a Trek hybrid from 2018

That little gauge said the chain was at 0.75 wear but my old 12 inch ruler trick showed fine, now I'm wondering how many chains I've let go too long over the years, has anyone else found the ruler method to be way off compared to a proper tool?

Seven chains ruined because of that ruler trick.

I gotta say I see it differently. The ruler trick can be annoying for sure but I think a lot of times it's the only way to get consistent measurements when you're working with old houses that aren't square. Seven chains ruined sounds like there was probably something else going on with the material or the installation itself. Maybe the walls were really out of whack or the cuts weren't adjusted for the actual wall condition. I've seen plenty of straight edges give people a false sense of security too.
