SYSVIEW for DB2 Batch Reporting Query BTSTASM1

Issue/Introduction
Running the DB2 Statistics Batch Report BTSTASM1 to find out the HWM for MAXDBAT Usage. The Output Report contains a section " DISTRIBUTED DATA FACILITY " which has a field for MAX DBAT for ACTIVE and INACTIVE.
This value seems to remain the same until DDF is restarted. For Example, if for Monday the Maximum DBAT had reached the limit say 500, the report shows 500. When the report is run say for the next Friday, even though the Maximum DBAT hasn't reach 500 on Friday, the report still shows 500.
It seems like this field is not getting reset unless DDF is restarted. Is it possible to find an exact value for the Maximum DBAT that was used for each day for some performance analysis?
Environment
Release : 20.0
