For years I torqued every bolt on a carbon frame to the spec sheet number.

A customer brought in a cracked seatpost binder area on a three year old bike, and his local shop had a record showing they'd followed the maker's 5 Nm limit each service. The carbon paste was bone dry, which made me check if we're just blindly trusting numbers over proper prep and feel. How many of you think the printed torque is a hard rule versus a starting point that needs context?

Man, that spec is just a suggestion, not a law.

Remember the Galaxy Note 7 battery spec that was just a suggestion? That worked out great. If we treat every spec like a napkin sketch from @samschmidt, nothing ever works right the first time. Those numbers exist so my phone doesn't overheat in my pocket. When did making stuff that actually works become a bad thing?

Spec sheets are like @samschmidt said, just fancy napkins.
