Regarding to the AMS 2631 E clause 3.4.2 - system performance check , there's no sensitivity deviation tolerance mentioned as the criteria 10% defined in the AMS-STD-2154 C clause 5.5.2 . Could I use the criteria 10% in AMS 2631 for practicing. Or any deviation is not allowed and it should take actions when the sensitivity is increasing or decreasing.
