ReportIntervalCount
An integer-value representing the value of a counter associated with the measurement taken during a previous report interval. An implementation supporting a history of N report intervals with IntervalCount(1) and IntervalCount(N) representing the most and least recent intervals, respectively, the following applies at the end of each report interval: - Discards the value of IntervalCount(N). - The value of IntervalCount(i) becomes that of IntervalCount(i-1) for N >= i > 1. - The value of IntervalCount(1) becomes that of CurrentCount.
