I have been asked by several co-workers on the following two questions:
1. Is there a mathematical equation or algorithm behind the summarized reports? If so, what is it? If not, how is the data rolled up?
2. Does the report writer includes all downtime including standard outage for things like patching, meaning that the availability for outages caused by an incident is really higher than shown?
Answers to these two questions would be very helpful if someone knows them.
