Honestly my shocks don't build pressure during the course of a race day. Mine build it from elevation changes when I drive to the tracks. I live at or slightly below sea level and in order to get to some of the tracks I'll hit 2000 feet above. My shocks will act like pogo sticks if I don't bleed them.
