Does ACE perform Exception Test for Output Tags?

We have a naturally scheudled ACE calculation with 14 trigger tags with the calculation results written to several output points in PI. The excdev and excmax have been configured for 1 eng. unit and 5 minutes respectively. When I check the archive values for the tag, though, it appears to have multiple repeated values that should have been filtered by the exception deviation. I've included some of the archive data below:

 

The ACE manual states that ACE reports by exception but does it actually perform an exception test using the excdev and excmax values defined for the output points or does it simply report every value that is different from the previous value to the PI server?
