If the chain checker shows good, a ruler isn't going to make it look bad.
If the chain checker shows bad, THEN measure with the ruler to verify.
The .5% mark on my CC is really .25%. As long s I know what it is, it's a quick tool that tends to keep my hands much cleaner.
IF I use a ruler/tape, I measure a 3' section and reduce my error from parallax etc. to 1/3. I don't know why people seem to insist on measuring just 12"?
