Your altitude or temperatures need to vary pretty dramatically for that to make a big difference out on the trail. I know I've personally experienced it when I set pressures inside my cool basement suite, then go ride without checking in the super hot summer sun, or super cold winter (probably a 15-20C difference either direction). I'm pretty damn in touch with my pressures these days, where I can definitely feel +/- 1 psi difference, and checking right before the ride seems to do it for me, but I'm also not usually descending more than 800 meters either.
