Just found out 90% of chain wear gauges are inaccurate

I read a test from a bike magazine that checked 10 different chain wear tools and only one gave the right reading every time. Has anyone else double checked their gauge against a ruler?

Use a ruler and check it yourself. I did this last month and found my fancy Park Tool gauge was off by almost a full 1/16th inch on a new chain. The notch wore down fast too. Now I just use a cheap ruler from my toolbox and it works better than anything else.

@max808 did you check the ruler against something else first too? I'm just wondering if maybe the ruler has its own wear and tear that could throw things off even more lol.
