I think we have come to same conclusion in the past. The story I relate is someone who worked for me proudly presenting his chain measuring tool and telling me that my chain was well and truly shot and needed replacing. Trouble was... the chain was but weeks old and had hardly been ridden since being fitted to that bike.
The ruler is truth.
