An assignment service-level agreement (SLA) is configured with the following details:
*Initial urgency: 15
*Assignment ready: Timed delay of 2 hours
*Goal: 1 hour and increase urgency by 10
*Deadline: 2 hours and increase urgency by 15
*Passed deadline: 1 hour, increase urgency by 10, and limit events to 10
Assuming no other urgency adjustments, what is the assignment urgency 4.5 hours after the case reaches the assignment?
