Q. ATS documentation used to specify <1% difference in output comparison, and now it specifies <2%.


Answer:

Apparently, this was an inconsistency between our SVVP and the ATS document that was corrected for the 9.5.1.5 QA&R release in 2013. Our SVVPs have always stated this tolerance level as 2%. See below snapshot from an SVVP dating back to 2009.
