ddboost streams show history command

hi there ..

Can you please advise the output of ddboost streams show history output number is the result of average amount during set interval?

Or the result of Max( or accumulated)  number?

ddboost streams show history

                {storage-unit | tenant-unit }

                [interval ]

                [last {hours | days | weeks | months} |

                start [end ]]

                                       Show streams history per storage-unit

I have checked https://support.emc.com/docu78753_Data-Domain-Operating-System-6.0-Command-Reference-Guide.pdf?language=en_US  Page 142 for ref ...but does not say ...

thanks !
