To cut a long story short, just read this paragraph:
According to Renault engineers, an F1 tyre works best under a very slight wheel spin. If there's too much wheel spin, the tyres lose traction and acceleration is greatly reduced. Traction control plays a crucial role in assuring constant acceleration when coming out of the corners. "Wheel speed sensors are attached to the four wheels of the car" says Chevrier. "At any moment, the computer knows the exact speed of the car from the front wheels sensors. By comparing the speed of the front wheels to that of the rear wheels, the computer is able to detect the slightest wheel spin. Wheel spin occurs when the speed of the rear wheels exceeds by a certain value that of the front wheels. We do track testing and set the traction control to come into action when the wheel speed difference reaches 103%. Then, we change that value to 102%, and then to 101%. We then compare those changes to the differences in lap times and see what is most efficient."Traction control allows a bit of wheel spin, whereas throttle help DOES not. A bit wheelspin does increase laptimes, as they say there. If throttle help DOES NOT allow wheelspin at all, it MUST lead to worse laptimes.
