Using 1 workspace and 1 table as an example, if there are only 11 records of this table that have been updated, i.e. the _DIFF contains 11 records having I/U/D in wm_code column for the workspace:
COUNT(*) |WM_DIFFVER                                     |WM_CODE
---------|-----------------------------------               |-------
884      |AP002000000979002000000979, LATEST |NE    
11        |AP002000000979002000000979, LATEST |I      
11        |LIVE, LATEST                                         |NE    
895      |DiffBase                                                 |NE    
849      |LIVE, LATEST                                          |I      
2206    |LIVE, LATEST                                          |U      
2171    |AP002000000979002000000979, LATEST |NC    
2171    |DiffBase                                                 |NC    

While the number of records for the same workspace in the staging table are more than 14000, 11 with WM$FLAG = 6 (the 11 records inserted) and 14545 WM$FLAG = 4 :
COUNT(*) |WM$FLAG
