My 2009 had 15 hours before it felt like the suspension was getting broke in. The first ride, I left it at stock clicker settings, and a only set the sag. It was way stiff and rebound seemed way too fast. I backed off the compression to full soft, then went 5 clicks toward stiff side and have left it there. Also set the rebound accordingly. Now, after ~20 hours, it feels pretty good to me from a compression standpoint. I have noticed a pogo effect over some sharp edged bumps and roots this past weekend, so some more work with the rebound clickers is needed. Big hits, g-outs, and log jumps on the SACHS is better than any suspension I have ever had.
Overall, I like the action better than the WP stuff on my '08 300XC, I never found even a happy medium.
