Clarification for PercentGood calculation for Historian 4 data |OPC UA Standard|Forum|OPC Foundation

Hello Team,

I would like to understand the calculation for PercentGood (OPC Aggregates definition):

Input: Historian 4

Interval: 01:20 to 01:36

Processing Interval: 16 Sec

Formula Used:

PercentGood = (DurationGood / ProcessingInterval) * 100

From the document for the given Interval Duration good value is 7001 

so when we put the same value in the above formula:

PercentGood = (7001/16000)*100 = 43.75625 

but in the document the PercentGood value for this interval is 70.003

Please explain how?

Regards,

Saurabh
