I don't have good data for the Victor SP, but I would assume it has a linear response curve like the rest of the more recent motor controllers. This could likely make a difference in driver practice and autonomous programming for small movements at low voltages.
Yup - we noticed

In the grand scheme of things it didn't make a big difference but yes, the two robots behaved slightly differently. In this game it was largely about pedal-to-the-metal driving whether it was to fly over a defense or get to a boulder, so it didn't have a big impact on our driver training. We thought about making adjustments (squaring the inputs, etc.) but decided it didn't really matter.
