SLA Breach details (hours, levels)

Being able to have more information provided about how far your SLA has been breached (such as a percentage or graph) or being able to define different breach 'levels' would provide helpful information to know to what degree the SLA has been breached.

For example, with a 24hr expected SLA response time, if you were to respond at 25hrs it would be helpful to know how close to the SLA you are - in the current state, a response at 25hrs and a response at 2 weeks would be considered an equal amount of 'breach'.
