Slight thread drift
When the going is good, it's fine (just about). However with just one distraction, pilots then have to make up the time somehow. And that is when corners are cut....... or gross errors not noticed.
And here is where we pilots make the rod for our backs. So time conscious, and proud of being able to make an on-time departure, we find a way to do more and more in the allotted time, proving to our employers that the job can be done with less and less time. We should run late when conditions contrive to delay normal preparation and just accept the appropriate delay code.
