Per user guarantee levels. i.e 100% outage for 1 user is equivalent to a 0% availability guarantee. The relationship between client and service is the same irrespective of the number of clients the service has - a number which means exactly nothing to the client. But more importantly, availability numbers are for informing a client about how much incidents outside their house can affect them, and reasonable courses of action to take when it does. When using the numbers internally, the fudged number is equally misleading. Unfortunately there exist fewer adversarial relationships internal to an organisation to prevent these short sighted statistical nonsenses.
