86% on both was 'Warranty Torque' on the A model. That was what you set in the cruise, effectively twin engine max continuous. RRpm in the first few year was 100% at all levels but it was found that as one climbed increasing the Rrpm to 107% @ 5,000 ft. increased the airspeed and reduced both vibration and SFC.
Later on in life it was found that beeping up to 107 in the hover and dragging it down to 100% just before you threw it over the side of a helideck gave you a better chance of survival should an engine fold on you.
