It really depends on a bunch of different variables. Highway or city miles? A lot of High rpm or rarely? How long do you warm up the car? I would say to pull a spring at 20K or 25K and check the pressure. If theyre good, put it back in. 5K later pull a different spring and test again. Lather, rinse, repeat.
