I started off thinking that the shock was there to make the ride seem like a cadillac. It is not. The purpose of the shock is to smooth out small frequency vibrations from the trail and to cushion large impacts from rocks, landing, jumps ... Don't let the air pressure go to far below the chart or the shock can't do it's job. It will kill your pedaling efficiency and your ability to climb. Also if you have rebound adjustments be sure it is set to rebound fast enough that is is returning to full extension before the next set of bumps. To low of a rebound setting will cause it to sag lower and lower over a series of bumps and you will run out of travel.
