During my first few months as an engineer a marketing type gave a presentation regarding his market survey.
He started by saying the LSD (least significant difference) was some number. The he pointed to our position on top of the graph and said we were the leader. But, our nearest competitor was less the the LSD below us.
When I pointed this out he grumbled a bit and revised his statement to say we were among the best.
It did not take me too long to figure out that my comment was not all that welcome.
Live and learn.
