When you change the year portion of the start date, the year portion of the end date changes to the same number. I don't think this should happen.
In the summary by record type, it would be more informative if you broke down information by record subtype for those records that support subtype. You should also make that summary available under Reports.
The Dataset Activity report shoud inclide items like EXCP counts, DCB information, volsers, device addresses, for records that support such info (14, 15, 17, 18, 6X).
