Mine has most of that. before i started it was 6 months between alerts. 1 day off and 1.5 to 2 times the alert period and recovery period with good mins and good people.

the only downside is a small rotation (3 people 1 week each) and some serious scaling issues which have made the pervious few months much worse than earlier ones. though we also have management buy in to fix the less than good parts.
