PDT output SysAgent Method query

I’ve been doing some analysis on our system trying to find areas of improvement. When converting PDT server logs to SQL you get a nifty summary of all of the methods fired, frequency longest execution time, shortest avg etc.

What I have noticed under the SysAgent method We see the Update but it is post ceded with a BAQ name

for example Update(POL_InvoiceMissed)

I am hoping that someone can shed some light. When I look at the Update method on SysAgent the input and output is ds Ice.Tablesets.SysAgentTableset.

It does not make a whole lot of sense. In the data caputure (of 1 week) it only gets fired 6 times, but I am curious.
