Yup, you leave the rebound all the way in. Never touch it again. And the compression, after screwing it all the way out, for the softest setting, screw it in as needed to get the ride where you want it. You may have to go six lines in on the compression, which is one full revolution. And for the dunes, probably two full revolutions in or six lines. And again, each line on the compression equals a click. And when I was doing my compression, the screw, or slow compression was mostly the one I used. The 17 mm nut is for high-speed, which is usually landing off of jumps. Mine handles the jumps pretty well no matter what, so that's why there wasn't much need to adjust the high-speed compression. Your results may vary.
