As jrd22 as said: "You do need to use more throttle from a stop compared to a fixed blade" and as the boat was always trying to gain speed, just to be stoped by the next have, I believe that in these conditions a fixed prop woud have been more efficient.
Thinking overnight I may have the auto-pitch adjustment bass ackwards in my head but I have never been without all the power I needed. The waves you are speaking of are 2-3 times more than I have ever seen..... and I plan to keep it that way. The only 'test' I have ever given my AutoProp was straight into a 20kt wind with an opposing tide in L.I Sound creating very steep, short period 5-6 footers (not meters ). There was salt water raining from the rigging but I was holding 5-6kts easily with only a slight increase in throttle. Maybe unlike your experience my Auto was always in Power mode and never coasting down your much higher waves so it just kept pulling like a tractor ignoring the waves completely.
