have you heard of the 50-50 90 theory?

when there is a 50/50 chance of a good or bad outcome, 90% of the time the bad outcome will prevail. It's related to Murphy's law, of course.

This dozer could land on the track, and be no further trouble for the day, OR, it could land on the side, and cause the rest of the day to be an effort to upright it.
