The valve gets stiffer, the damping force increases to deal with whatever is going on, then it drops back down to the soft setting. This all happens in fractions of a second.

**(Note that "full soft" is /= comfort mode. Full soft means no current being sent, no active control, absolute minimum damping force. Comfort mode typically has some level of active control, just less of it than normal and sport modes)
