Basically at 100% spring the force is scaled linearly through the travel range (green line), you can also have a stiffer response, but saturated at travel edges (black line). The endstops have a very rapid rise of torque response vs travel giving the illusion of more force.
It's possible to increase spring gain above 100% using the spring "Gain Map" tool
