It's not totally clear in the report what the SOP response actually was, but to my way of thinking the Green Dot check should be a readout, from both pilots, of their GD speeds, not one read it and the other say "checked". If one is forced to read the number off somewhere, there is a much better chance of the check actually working. On more than one occasion I've said "checked" out of habit but not actually done it.
The other aspect/check that I thought was prone to failure was "both crewmembers to silently verify..." I would class that as a purely an airmanship check and not part of a robust procedure.
The other part of the report which was fascinating was that on Distraction Management. A huge threat, IMO, and hardly ever covered.
