AFSDK and Exception Deviation

As I understand, exception deviation testing is done before it goes to the PI Snapshot subsystem.  If I am developing an application using the AFSDK, and calling AFListData.UpdateValues(), will exception testing be done automatically on the PI Server?  For example, if I call UpdateValues on a tag with the same value every second over ten minutes, with exception settings of ExcDevPercent = 1, ExcMax = 600, Compressing = 0, would I get 1 value or 600 hundred values in the archive.

 

What I would like is to have settings where I get all data changes, but I do not want to flood the archive if the value is not changing.  Any suggestions?
