As a user, I want to see the waiting time due to exogenous factors.
This is the waiting time due to external factors that cannot be identified from the event log. To identify this waiting time, subtract all identified waiting times from the total handoff duration:
WTexogenous = handoff_duration - WTresource_cont - WTresource_unav - WTbatching - WTprioritization
