^This^ 40psi for a 130lb rider is insane. At 160lb I'd probably crash every other corner w/ 40.
ETA: The 'less til you pinchflat' is not the smartest thing either. You may find your best pressure results in a pinch flat or 2 on the most rough terrain but it's perfect the rest of the time. Don't over inflate to avoid pinch flats, you'll not be happy the 99.999% of the time you're not pinch flatting.
