Couple of interesting points in the context of our discussion - 0.5G as the number to stay above, and recovery is gentle aft cyclic followed by left cyclic once disc is loaded. No mention of collective whatsoever.
IIRC the Robinson standard recovery procedure is the same - immediate but gentle aft cyclic followed by left cyclic once the disc has loaded.
