Especially for foam based classes, traction changes over the course of the race as the compound fades. We can't manually adjust the Dual Rate every few minutes to make up for the change.

If a Radio maker made a function that allowed the expo to change over the course of a race. With the ability to change the curvature as well of the expo.

Example:
Eight minute race goes from 60% to 70%. With the major increase/ramp happening around the 5 minute mark.

EDIT: Meant Dual Rate NOT Expo.
