This quote is also from my addendum (supplement) to my first report:
(Per documentation) a "critical ground" is the same as a "designated ground", with "designated ground" being the preferred term. This fits in with BCAG’s general philosophy to rename things to make them seem as benign as possible to the inspector to keep them from trying to inspect the product. An inspector is much more likely to roller stamp a "designated ground" than a "critical ground." An inspector with some ethics may actually want to ensure a "critical ground" passed resistance requirements and assembly requirements (the right parts being used to ensure no corrosion by galvanic incompatibility to ensure the "critical ground" will last over time).
