This modify call tells the rule engine to "look at this DutyHourTotal object again." The rule should 
just keep firing. If there were some condition on the DutyHourTotal that eventually was false it 
would stop but I am surprised you only see it fire twice and not forever. Perhaps there are side 
effects of setNrHours() that cause one of the other conditions to fail.
