There's no corrective input or oscillation of force in the same way throughout the trace, with the exception of some corrective action at 0:49. The lack of oscillations at high speed (0:05-0:07 and 0:39-0:40) suggest that the car is more stable. I've not seen steering torque data before though, so perhaps this is normal.
Interesting point. Our drivers tend to like a car that is pretty loose at low speed. The courses that it runs on tends to have a lot of very tight hairpins and such so drivers like a car that can rotate at low speeds. Conversely they tend to like a car that pushes (at least a little) at higher speeds (in this case higher is like 45+ mph). We tend to run our Cp pretty substantially rearward of our CG because most of the high speed maneuvers are big offset slaloms which can get hairy with a car that is loose.
