I simply don't buy the story that tightening the connector makes
a consistent 60 nanoseconds difference on a signal.
It can add a signal where one was missing before, but it does
not change the timing of a signal that already made it through
by a consistent 60 nanoseconds.

Never attribute to malice what can adequately be explained by incompetence.
