In our last monthly usage report we have numerous (but not all) ports' 95/5 usages being calculated with the transmit and receive values added rather than the highest value being used.
If it helps here is our report gen code:
DECLARE @StartDate DateTime
DECLARE @EndDate DateTime
SET @StartDate = DATEADD(d, DATEDIFF(d, 0, DATEADD(m, -1, DATEADD(d, 1 - day(getdate()), getdate()))), 0)
SET @EndDate = DATEADD(ms, -2,DATEADD(d, DATEDIFF(d, 0, DATEADD(d, 1 - day(getdate()), getdate())), 0))
