I tried it with both extension arms, hoping that by using the longer brackets, it would lower the load enough to get rid of that whippy feeling. It didnt work. They rate the rack to be sutible for around 13 lbs; I came nowhere near that and had issues. Here's a pic for reference for those who haven't seen a Randonneur rack

The pic shows the rack installed with the standard brackets, and you can see how high the load sits. I installed the longer brackets after this pic was taken, which were four inches longer, but not nearly long enough to prevent the whippy feeling.
I suspect the "whippiness" you describe is due the the fact that the load is cantilevered off the seat post with no other bracing. A rack that mounts on the dropouts and seat stays (or brake bridge) doesn't have that problem in my experience, even when fully loaded for an extended camping trip.
