Torque bias of a clutch type starts at a positive value because of the breakaway torque. How much steeper it gets is dependent on tunable factors like ramp angle, active clutch plates, and in the case of the OS Giken I got for the FD, preload springs. I had mine specifically tuned to have minimal breakaway torque and a shallow slope to avoid rapidly increasing lockup with torque.
